Updates to a package uploaded to mentors.debian.net

[Grzegorz Niewisiewicz <grzegorz@niewisiewicz.pl>]

Hi!

I've created my first Debian package [1] and filed an RFS [2]. It
haven't generated much interest yet. I want to make some adjustments
to the package and I don't know how.

Lintian complained that there's no watch file. I added it and I'd like
to update my package. Should I increase the Debian revision and/or
mention the addition of a watch file in changelog or should I update
the package in place?

Regards,
Grzegorz
