Nathan Vegdahl 2dba228c76 Fix highlight code splitting graphemes.

endings, but could potentially have manifested with other
graphemes as well.

Gokul Soumya 394629ab73 Skip enclosed pairs in surround 
Surround operations previously ignored other pairs that are
enclosed within which should be skipped. For example if the
cursor is on the `,` in `{{a},{b}}`, doing `md{` previously
would delete the `{` on the left of `a` and `}` on the right
of `b` instead of the outermost braces. This commit corrects
this behavior.

Benoît CORTIER 6bdf609caa Remove RwLock for registers 
Registers are stored inside `Editor` and accessed without `RwLock`.
To work around ownership, I added a sister method to `Editor::current`:
`Editor::current_with_context`. I tried to modify `Editor::current`
directly but it's used at a lot of places so I reverted into this for
now at least.

Add :earlier and :later commands that can be used to navigate the full edit history. (#194) 
* Disable deleting from an empty buffer which can cause a crash.

* Improve on the fix for deleting from the end of the buffer.

* Clean up leftover log.

* Avoid theoretical underflow.

* Implement :before which accepts a time interval and moves the editor to
the closest history state to the commit of the current time minus that
interval. Current time is now by default, or the commit time if :before
has just been used.

* Add :earlier an :later commands that can move through
the edit history and retrieve changes hidded by undoing
and commiting new changes. The commands accept a number
of steps or a time period relative to the currrent change.

* Fix clippy lint error.

* Remove the dependency on parse_duration, add a custom parser instead.

* Fix clippy errors.

* Make helix_core::history a public module.

* Use the helper for getting the current document and view.

* Handled some PR comments.

* Fix the logic in :later n.

Co-authored-by: Ivan Tham <pickfire@riseup.net>

* Add an alias for :earlier.

Co-authored-by: Ivan Tham <pickfire@riseup.net>

* Add an alias for later.

Co-authored-by: Ivan Tham <pickfire@riseup.net>

* Run cargo fmt.

* Add some tests for earlier and later.

* Add more tests and restore the fix for later that diappeared somehow.

* Use ? instead of a match on an option.

Co-authored-by: Ivan Tham <pickfire@riseup.net>

* Rename to UndoKind.

* Remove the leftover match.

* Handle a bunch of review comments.

* More systemd.time compliant time units and additional description for the new commands.

* A more concise rewrite of the time span parser using ideas from PR discussion.

* Replace a match with map_err().

ahkrr e2d780f993 fix: 2 panics while setting style + off by 1 
The panics would occur because set_style 
would draw outside of the the surface. 
Both occured using `find_prev` or `till_prev`
In my case the first panic! would appear
in a terminal with around 80 columns 
in helix/README.md going to the end of the file
with `geglf(`
the second with `geglfX`
The off by one fix ensures that `find_nth_prev` 
starts at the first character to the left

Benoît CORTIER 8a29086c1a Fix panic when moving over unicode punctuation 
`is_ascii_punctuation` will only work for ASCII punctuations, and when

`Unknown`.

Blaž Hrastnik 9821c4dd3b Optimize Changeset::is_empty() 
Checked the ASM output for these three options:

pub enum Operation {
    /// Move cursor by n characters.
    Retain(usize),
    /// Delete n characters.
    Delete(usize),
    /// Insert text at position.
    Insert(String),
}

pub struct A {
    changes: Vec<Operation>,
    len: usize,
}

impl A {
    pub fn is_empty1(&self) -> bool {
        match self.changes.as_slice() {
            [] => true,
            [Operation::Retain(_)] => true,
            _ => false,
        }
    }

    /// `true` when the set is empty.
    pub fn is_empty2(&self) -> bool {
        let len = self.changes.len();
        len == 0
        || (
            len == 1
            && self.changes[0] == Operation::Retain(self.len)
        )

    }

    pub fn is_empty3(&self) -> bool {
        match self.changes.as_slice() {
            [] | [Operation::Retain(_)] => true,
            _ => false
        }
    }

}

Blaž Hrastnik b0b5451c38 Since insert preceedes deletes, follow that ordering in Transaction::changes. 
Produces the same output but will take the happy path.
