[Adding comp.lang.perl.misc because this is now partly a Perl question
 as well as an Emacs question.  I hope this doesn't offend anyone.]

Doh!  It's so easy to forget emacs's command-line processing.  

Now I know why 
  $ emacs -f mail-mode foo.mail 
didn't seem to do anything!

I think I'm on the right track now, but I'm having problems with the
fact that the Perl program reads STDIN, processes it and stores the
results in a temp file.  When the Perl program gets to this line:

   my $status = system('emacs', '-nw', $temp_file, '-f mail-mode');

Emacs produces this error:

   standard input is not a tty

and doesn't run.  If I add the --batch option to the emacs command,
emacs runs and quits (it doesn't come up interactively), so that's not
the solution.
