- Rename module from `:completion selectrum` to `:completion vertico`
- Rename all files involved
- Do *not* yet rename all the functions, as that messes up git's rename
detection.
some doom functions check the completion module with `fboundp`'s instead
of `featurep!`, and counsel can be loaded by using e.g. `lispy`. we add
temporary fixes for this by checking for selectrum stuff first, but this
should be given a more robust fix later on
also we document the selectrum PR's hacks in the TODO.org
see discussion on #5013
Changes the behavior of
doom/backward-delete-whitespace-to-column
to only delete to the closest tab column if there
is only whitespace between point and BOL.
This coincides with what the comments state to be
the original intent.
