m4/groff.m4 (GROFF_PAGE): Refactor.
* m4/groff.m4 (GROFF_PAGE): Use 'grep -q' instead of redirecting
standard output to null device. The '-q' option was standardized in
POSIX Issue 5 (1997). Also drop the redirection of the standard error
stream; we have already checked the file named in "$descfile" for
existence and readability. grep should not emit diagnostic messages.
