Determine whether to use a margin of 0 or 1 when uncommenting (#476)
* Implement `margin` calculation for uncommenting

* Move `margin` calculation to `find_line_comment`

* Fix comment bug with multiple selections on a line

* Fix `find_line_comment` test for new return type

* Generate a single vec of lines for comment toggle

`toggle_line_comments` collects the lines covered by all selections into
a `Vec`, skipping duplicates. `find_line_comment` now returns the lines
to operate on, instead of returning the lines to skip.

* Fix test for `find_line_comment`

* Reserve length of `to_change` instead of `lines`

The length of `lines` includes blank lines which will be skipped, and as
such do not need space for a change reserved for them. `to_change`
includes only the lines which will be changed.

* Use `token.chars().count()` for token char length

* Create `changes` with capacity instead of reserving

* Remove unnecessary clones in `test_find_line_comment`

* Add test case for 0 margin comments

* Add comments explaining `find_line_comment`

Add object selection (textobjects) (#385)
* Add textobjects for word

* Add textobjects for surround characters

* Apply clippy lints

* Remove ThisWordPrevBound in favor of PrevWordEnd

It's the same as PrevWordEnd except for taking the current char
into account, so use a "flag" to capture that usecase

* Add tests for PrevWordEnd movement

They did not preserve anchor positions and were only used
for textobject boundary search anyway so replace them with
simple position finding functions

* Rewrite tests of word textobject

* Add tests for surround textobject

* Add textobject docs

* Refactor textobject word position functions

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.

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.
