Fix initial highlight layer sort order (#5196)
The purpose of this change is to remove the mutable self borrow on
`HighlightIterLayer::sort_key` so that we can sort layers with the
correct ordering using the `Vec::sort` function family.
`HighlightIterLayer::sort_key` needs `&mut self` since it calls
`Peekable::peek` which needs `&mut self`. `Vec::sort` functions
only give immutable borrows of the elements to ensure the
correctness of the sort.

We could instead approach this by creating an eager Peekable and using
that instead of `std::iter::Peekable` to wrap `QueryCaptures`:

```rust
struct EagerPeekable<I: Iterator> {
    iter: I,
    peeked: Option<I::Item>,
}

impl<I: Iterator> EagerPeekable<I> {
    fn new(mut iter: I) -> Self {
        let peeked = iter.next();
        Self { iter, peeked }
    }

    fn peek(&self) -> Option<&I::Item> {
        self.peeked.as_ref()
    }
}

impl<I: Iterator> Iterator for EagerPeekable<I> {
    type Item = I::Item;

    fn next(&mut self) -> Option<Self::Item> {
        std::mem::replace(&mut self.peeked, self.iter.next())
    }
}
```

This would be a cleaner approach (notice how `EagerPeekable::peek`
takes `&self` rather than `&mut self`), however this doesn't work in
practice because the Items emitted by the `tree_sitter::QueryCaptures`
Iterator must be consumed before the next Item is returned.
`Iterator::next` on `tree_sitter::QueryCaptures` modifies the
`QueryMatch` returned by the last call of `next`. This behavior is
not currently reflected in the lifetimes/structure of `QueryCaptures`.

This fixes an issue with layers being out of order when using combined
injections since the old code only checked the first range in the
layer. Layers being out of order could cause missing highlights for
combined-injections content.

rework positioning/rendering and enable softwrap/virtual text (#5420)
* rework positioning/rendering, enables softwrap/virtual text

This commit is a large rework of the core text positioning and
rendering code in helix to remove the assumption that on-screen
columns/lines correspond to text columns/lines.

A generic `DocFormatter` is introduced that positions graphemes on
and is used both for rendering and for movements/scrolling.
Both virtual text support (inline, grapheme overlay and multi-line)
and a capable softwrap implementation is included.

Separate jump behavior from increment/decrement (#4123)
increment/decrement (C-a/C-x) had some buggy behavior where selections
could be offset incorrectly or the editor could panic with some edits
that changed the number of characters in a number or date. These stemmed
from the automatic jumping behavior which attempted to find the next
date or integer to increment. The jumping behavior also complicated the
code quite a bit and made the behavior somewhat difficult to predict
when using many cursors.

This change removes the automatic jumping behavior and only increments
or decrements when the full text in a range of a selection is a number
or date. This simplifies the code and fixes the panics and buggy
behaviors from changing the number of characters.

Fix transaction composition order in History::changes_since (#4981)
* Add a undo/redo split test case for crossing branches

* history: Switch up/down transaction chaining order

The old code tends to work in practice because, usually, either up_txns
or down_txns are empty. When both have contents though, we can run into
a panic trying to compose them all since they will disagree on the
length of the text. This fixes the panic test case in the parent
commit.

Michael Davis 4a103db622 Apply inversions to Views on undo/redo
When using undo/redo, the history revision can be decremented. In that

of the document.

Use TreeCursor to pretty-print :tree-sitter-subtree (#4606)
The current `:tree-sitter-subtree` has a bug for field-names when the
field name belongs to an unnamed child node. Take this ruby example:

    def self.method_name
      true
    end

The subtree given by tree-sitter-cli is:

    (singleton_method [2, 0] - [4, 3]
      object: (self [2, 4] - [2, 8])
      name: (identifier [2, 9] - [2, 20])
      body: (body_statement [3, 2] - [3, 6]
        (true [3, 2] - [3, 6])))

But the `:tree-sitter-subtree` output was

    (singleton_method
      object: (self)
      body: (identifier)
      (body_statement (true)))

The `singleton_method` rule defines the `name` and `body` fields in an
unnamed helper rule `_method_rest` and the old implementation of
`pretty_print_tree_impl` would pass the `field_name` down from the
named `singleton_method` node.

To fix it we switch to the [TreeCursor] API which is recommended by
the tree-sitter docs for traversing the tree. `TreeCursor::field_name`
accurately determines the field name for the current cursor position
even when the node is unnamed.

Capture word parts while calculating shellwords (#4632)
This fixes an edge case for completing shellwords. With a file
"a b.txt" in the current directory, the sequence `:open a\<tab>`
will result in the prompt containing `:open aa\ b.txt`. This is
because the length of the input which is trimmed when replacing with
completion is calculated on the part of the input which is parsed by
shellwords and then escaped (in a separate operation), which is lossy.
In this case it loses the trailing backslash.

The fix provided here refactors shellwords to track both the _words_
(shellwords with quotes and escapes resolved) and the _parts_ (chunks
of the input which turned into each word, with separating whitespace
removed). When calculating how much of the input to delete when
replacing with the completion item, we now use the length of the last
part.

This also allows us to eliminate the duplicate work done in the
`ends_with_whitespace` check.

Michael Davis 3e84434c69 Fix panic from indenting on tree with errors
`deepest_preceding` is known to be a descendant of `node`. Repeated
calls of `Node::parent` _should_ eventually turn `deepest_preceding`
into `node`, but when the node is errored (the tree contains a syntax
error), `Node::parent` returns None.

In the typescript case:

    if(true) &&true
    //      ^ press enter here

The tree is:

    (program [0, 0] - [1, 0]
      (if_statement [0, 0] - [0, 15]
        condition: (parenthesized_expression [0, 2] - [0, 8]
          (true [0, 3] - [0, 7]))
        consequence: (expression_statement [0, 8] - [0, 15]
          (binary_expression [0, 8] - [0, 15]
            left: (identifier [0, 8] - [0, 8])
            right: (true [0, 11] - [0, 15])))))

`node` is the `program` node and `deepest_preceding` is the
`binary_expression`. The tree is errored on the `binary_expression`
node with `(MISSING identifier [0, 8] - [0, 8])`.

In the C++ case:

    ; <<
    // press enter after the ';'

The tree is:

    (translation_unit [0, 0] - [1, 0]
      (expression_statement [0, 0] - [0, 1])
      (ERROR [0, 1] - [0, 4]
        (identifier [0, 1] - [0, 1])))

`node` is the `translation_unit` and `deepest_preceding` is the `ERROR`
node.

In both cases, `Node::parent` on the errored node returns None.

This change processes the input as shellwords up-front and uses

Change syntax for suffix file-types configurations (#4414)
The change in d801a6693c to search for
suffixes in `file-types` is too permissive: files like the tutor or
`*.txt` files are now mistakenly interpreted as R or perl,
respectively.

This change changes the syntax for specifying a file-types entry that
matches by suffix:

```toml
file-types = [{ suffix = ".git/config" }]
```

And changes the file-type detection to first search for any non-suffix
patterns and then search for suffixes only with the file-types entries
marked explicitly as suffixes.

Fix multi byte auto pairs (#4024)
* Fix test::print for Unicode

The print function was not generating correct translations when
the input has Unicode (non-ASCII) in it. This is due to its use of
String::len, which gives the length in bytes, not chars.

* Fix multi-code point auto pairs

The current code for auto pairs is counting offsets by summing the
length of the open and closing chars with char::len_utf8. Unfortunately,
this gives back bytes, and the offset needs to be in chars.

Additionally, it was discovered that there was a preexisting bug where
the selection was not computed correctly in the case that the cursor
was:

1. a single grapheme in width
2. this grapheme was more than one char
3. the direction of the cursor is backwards
4. a secondary range

In this case, the offset was not being added into the anchor. This was
fixed.
