Original [patch] in case it gets garbled:
https://github.com/vadmium/pacman-arch/commit/0a71ece.patch

If the spirit of the change is appropriate but you’re not happy about
using the ”test” command, I’m happy to learn how to use the
Bash-specific way with double square brackets. Or someone who already
knows can translate it :)

Subject: [PATCH] Hack to detect Pacman-command-no-found error

Bash also uses exit code 127 for command-not-found errors, which can occur if
we lose access to the command given by $PACMAN. For instance after invoking
/etc/profile, $PATH may be reset.
