_man completion update for Solaris

[Danek Duvall <duvall@xxxxxxxxxxxxxx>]

After finally looking at Daniel's _man changes, I saw that there were a
couple of small (pre-existing) issues on Solaris.  Namely: the -s option
can take a comma-separated list of sections; and the man-index directory
gets thrown into the mix when it shouldn't.  This patch takes care of those
two things.

I don't know if the comma/colon section separation should just be generic
-- it's safe to do on Solaris, since although we don't recognize the
separator, we don't have any sections that have colons in them -- but I
don't know if it's compatible with the third if clause there.

I also didn't protect the /man-index/ removal with an OSTYPE check because
that seems safe enough on any OS, but there may be no reason not to do
that, either.

Thanks,
Danek
