Pgnus-0.33: bug in "mailcap-possible-viewers"

[Lloyd Zusman <ljz@asfast.com>]

I found a small bug in the `mailcap-possible-viewers' routine in the
`mailcap.el' file in pgnus-0.33.  The `minor' parameter sometimes gets
passed in as `nil', and this causes `string-match' to fail.  I'm not
sure under what conditions this parameter gets set to `nil' ... this
might have to do with badly formed MIME headers in the message being
parsed ... ???

But whatever the case, the enclosed patch seems to fix the problem.
Use the `-b' option with `patch', since my `diff' program might have
have messed with the leading white space.

By the way, today is the first day that I tried anything from the
pgnus series.  My congratulations to you, Lars ... your MIME-handling
code works great!
