Subject: vcsh: list_untracked(): Avoid `cut`; speed up `-r`
X-Git-Url: https://git.madduck.net/code/vcsh.git/commitdiff_plain/3a72a809b8681ed08ec45065089a5bd7d1b8cf4d?ds=inline;hp=--cc

vcsh: list_untracked(): Avoid `cut`; speed up `-r`

Avoid spawning `cut` and speed recursive mode up from "takes several seconds on a
current machine" to "instant".

Thanks to Thorsten Glaser.
