Yeah, looks like something that should be fixed. In fact, that whole
function needs some overhaul -- the magic 4096/4086/4087 numbers in it
are pretty yucky and make it hard to tell what's going on. That should
use a #define'd constant. Also, the user= field should probably be
fixed so that it uses parse_username() too.

Care to send a patch? If not, I'll plan to fix that sometime before the
next release.

Thanks,
