I can't think of a case where a URL would not start at a word boundary.
Let's add that to the regex. In addition to correctness, this also
slightly improves performance because matching can stop earlier.
$ HOME=$PWD hyperfine -w 1 'git checkout HEAD'{~,}' -- :/rc/filetype/markdown.kak && ./kak.opt big_markdown.md -e "hook global NormalIdle .* quit" -ui dummy'
Benchmark 1: git checkout HEAD~ -- :/rc/filetype/markdown.kak && ./kak.opt big_markdown.md -e "hook global NormalIdle .* quit" -ui dummy
Time (mean ± σ): 1.123 s ± 0.022 s [User: 1.100 s, System: 0.027 s]
Range (min … max): 1.093 s … 1.174 s 10 runs
Benchmark 2: git checkout HEAD -- :/rc/filetype/markdown.kak && ./kak.opt big_markdown.md -e "hook global NormalIdle .* quit" -ui dummy
Time (mean ± σ): 1.019 s ± 0.026 s [User: 1.001 s, System: 0.021 s]
Range (min … max): 0.984 s … 1.051 s 10 runs
Summary
'git checkout HEAD -- :/rc/filetype/markdown.kak && ./kak.opt big_markdown.md -e "hook global NormalIdle .* quit" -ui dummy' ran
1.10 ± 0.04 times faster than 'git checkout HEAD~ -- :/rc/filetype/markdown.kak && ./kak.opt big_markdown.md -e "hook global NormalIdle .* quit" -ui dummy'
`x` is often criticized as hard to predict due to its slightly complex
behaviour of selecting next line if the current one is fully selected.
Change `x` to use the previous `<a-x>` behaviour, and change `<a-x>` to
trim to fully selected lines as `<a-X>` did.
Adapt existing indentation script to the new behaviour
An indent hook automatically adds whitespace, so it seems prudent to
add the hook to remove unwanted whitespace again. This is what we do
in most languages already.
This commit allows using the <semicolon> expansion in commands, instead
of `\;`.
It makes commands look more elegant, and prevents new-comers from
falling into the trap of using <a-;> without escaping the semicolon.
