Well, then, we should produce meaningful error messages on broken regexes,
instead of filling the server log.  Something like the code below should
do it...

unless (eval { local $_=""; /$grep/o; } or $@ !~ /regex/) {
    print "<b>$grep</b>: invalid regex!<br><br>\n";
} else {
    # Do our stuff
}

Should I get this working and check it in?
