Hello,
inlined diff (p0, hope that's not a problem) adds regex matching to alpm_list; useful for regular expressions in IgnorePkg etc.
I'll leave the actual usage up to you and hope it helps somehow :)

Holy cow, this is the oldest pacman-dev email still in my inbox. Anyone think this would still be useful?

Well if someone implemented an actual usage, we would be sure it works as intended and is useful :)
regular expressions in IgnorePkg sounds cool.
