Dear vcswatch developers,

could you please extend vcswatch to check if the upstream and
pristine-tar branches (if they exist) are aligned with the main branch
and its changelog?

For instance, for the past two months the master branch of pam contained
the sources for 1.7.0, but the upstream and pristine-tar branches were
still at version 1.5.3 because the corresponding branches and tags had
not been pushed.

Regards,
