"filter" prints bogus status messages, and will even occaisionally core dump
on a BSD system (including Ultrix). Trace back to half-successful attempt at
disabling the (bad) "tolower" macro definition in hdrs/filter.h.

Here's a diff to Elm/hdrs/filter.h to correct things. I'd advise not running
filter on a BSD unless this patch is applied- you probably won't realize
you're not getting all your mail. While I was at it, I re-instated the bell,
and also eliminated the redefinition of _IOFBF.

I think that I shall never see
A billboard lovely as a tree.
Perhaps, unless the billboards fall
I'll never see a tree at all.
