This adds two things I forgot in
9a7d8df4 (Avoid accidentally using environment variables in sh scopes)
Mea culpa, the problem was that I was skipping matches with "filetype"
because that's usually just a hook parameter as in "WinSetOption filetype=.."
rg --pcre2 '\b(?!filetype=)\w+=' rc/
So I missed these two cases where a shell variable is actually called "filetype".
The one in git.kak was not a problem because show_git_cmd_output is only
ever called with sane inputs. However, file.kak does use the filetype
environment variable for many mime types, for example:
filetype=somefiletype\''; echo -debug injection; nop '\' kak /dev/null
Will run the echo since /dev/null has mime type "inode/chardevice"
This commit addresses the following issues:
* highlight trailing space characters with the `meta` face, instead of
`PrimarySelection`
* make the regex more readable by using a capture group in stead of
`\K`
* specifically match space characters, not other horizontal whitespace
characters
* match two or more space characters

Note that the original reproducer doesn't seem to work anymore,
probably because of changes made to how lists are highlighted.
Fixes#911
Similar to Jinja, getting `eex` highlighting in *.ex files
will require users to setup a filetype hook similar to the
following:
hook global WinSetOption filetype=elixir %{
require-module eex
add-highlighter window/eex ref eex
}
This is done both to fix a circular dependency between the `elixir`
and `eex` modules, and avoid polluting `elixir` files with false
positives from `eex` highlighting given `eex` is framework specific
This fixed a weird bug where if you were typing in the top level scope of a
program (no indentation before statements), the `end`s wouldn't be inserted
for you.
The syntax highlighting has been broken down into 3 main categories:
string: string, array of words
variable: symbol, array of symbols
meta: regexp, shell execution
