FILEMATCH is never assigned to; the code that would do this is commented out.
What this variable WOULD contain were it assigned is the last filename-pattern
that did NOT expand into a list of files.  In the case of
	$ command foo*
for instance, where there are no files matching foo*, I believe FILEMATCH
would contain "foo*".  This is apparently a debugging aid.

P.S.  It only took 3 greps and a quick peek at service.c to arrive
at this conclusion, and I'm not very familiar with the Bourne shell.
(I hope I'm right; I didn't want to spend any more time on the matter.)
