I'm not sure why I added that message in the first place, but I
think was was because I was concerned about searching through
large files and showing the user what was happening, so the program
wouldn't appear to have crashed if it was taking a long time to go back 
to the last match.  The other searching commands do have messages
that can be printed while the searching is happening, like
"Searching subfile %s...", although they don't print messages like
"Going forward to next match...".  I don't know whether this message
is really necessary, but it seems harmless to include it.
