Furthermore, I just notice, there may or may not be a whitespace just
before the first opening parenthesis in the input filename. To remove
that if it exists and to leave it alone if it doesn't, the following
seems to work:
$> nn2=`echo "$fn" | sed -e
's%\(.*\)\s*(\([0-9]\{3,3\}\))\.[Jj][Pp][Gg]%\\1\2.jpg%'`;
where \s* matches zero or more whitespace.
Suggestions for improvement?
