What about the following patch:
it does copy the old ari.source.bug to ari.source.old
then it removes the line number field from each of the two files
(in order to avoid seeing only line number changes due to code insertion or
deletion),
and compares the two resulting files.
  If the generated diff contains a '>' sign, it means that
a new warning has been generated.

  The only drawback is that the line number also does not appear
on the generated email...

  If someone with good awk knowledge can tell me out to
substitute each line of the diff (without the line number)
by the corresponding line of the files with line numbers,
it would make the email better.
