Subject: [PATCH] pygmalion: use pure zsh instead of perl (#9210)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

My system doesn't have `perl` in $PATH, so using this theme clutters the
shell output quite a bit.

Turns out, the same thing can be accomplished in pure zsh (with
extendedglob).
