You're correct. I forgot to mention, but that was another bug I have
fixed locally.

I've thought about that as well, but I don't think it's a good idea to
overload the variable with multiple meaning.

But then again library users should be calling drw_fontset_getwidth(),
so maybe it's fine to overload the variable for internal usage. If
that's deemed acceptable then I can change it.

Anyhow, I've been using the patches on both dwm and dmenu, and so far
everything seems to be working as expected :)

I'll wait until tomorrow and give the patches another look with fresh
eyes to see if there's some edge case unhandled before sending them.
