[PATCH] send-email: support coloring dry-run output

It highlights sendmail command and subject lines. The most important
lines to me.

I'm no Perl expert. This patch is by no means for submission. But
maybe it'll motivate someone to do a proper patch.

This seems like it would be a useful patch for those of us using sendmail.
I'll admit I don't know any perl at all, but one bit seems a little
odd to me. Is there a reason you use 3 separate print statements to
deal with the colours on the Sendmail line, but a regex substitution
the second time? I have no idea which would be considered the better
practice but surely we should pick one and be consistent? Unless
there's some difference between the two that I'm missing.
Thanks
Angus

No reasons. It was what I had in mind at that time and it worked, so I
did not bother cleaning up or anything.
