grep can no longer find files with matches

[Henrik Enberg]

After the 2005-08-12 change to compile.el, M-x grep can no longer
automatically find files that have matches in them.  I just get the
following prompt when I hit "C-x `":

    Find this error in: (default Grep started at Sat Aug 13 04) ~/Mail/

This is caused by the second line of the *grep* buffer which reads
something like:

    Grep started at Sat Aug 13 04:45:07

Which causes the next-error to try to find a match in the file "Grep
started at Sat Aug 13 04:45".
