But the patch you proposed doesn't check for pipes.  It disables saving
time stamps when no file arguments are given.  This would mean
that "gzip <file1 >file1.gz" would not record FILE1's time stamp.

Of course gzip could behave differently for pipes than for other kinds
of files, but it's problematic to make pipes special cases.

The user can employ "gzip -n" when compressing.  That enables the
desired behavior, and it works now.
