Oh, sorry, we discussed this with Dan on IRC, and then I was willing to
answer the mail so that others can follow, and totally forgot.
When Dan asked me about these edge cases, I wasn't sure what to answer. But
when thinking back about it later, I thought about something similar to what
you just did for proving it was correct, so thanks :)

About the basename, I did what Dan asked, move mbasename from pacman.c to
util.c , and then use that instead.
That change and the Qo patch are both already in master.
