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'
