# Objective

Both https://github.com/zed-industries/zed/pull/59005 and
https://github.com/zed-industries/zed/pull/53789 introduced actions, at
the editor context, which allow to select the content between
brackets/delimiters, with the latter also adding an action to include
the brackets/delimiters too.

Shipping both would mean we end up with three distinct, but similar
actions:

* `editor: select inside enclosing bracket`
* `editor: select inside delimiters`
* `editor: select around delimiters`

As such, in order to simplify this, the changes in this Pull Request
remove the first action, while updating the logic for both `editor:
select inside delimiters` and `editor: select around delimiters` in
order to support continuous outwards expansion, like `editor: select
inside enclosing bracket` supported.

## Solution

* Remove `editor::SelectInsideEnclosingBracket` action, it's related
method and tests
* Updated `editor::selection::Editor::select_delimiters_impl` to use
`MultiBufferSnapshot::enclosing_bracket_ranges` instead of
`MultiBufferSnapshot::innermost_enclosing_bracket_ranges` so we can
traverse all bracket ranges and expand to the next one

## Testing

Besides manual testing, a new test case was added specifically for the
selection expansion support, namely
`editor::editor_tests::test_select_delimiters_expansion`.
