Bug#704924: debcommit -r should create a signed tag even when there are no uncommitted changes

[Joey Hess]

Package: devscripts
Version: 2.12.6
Severity: normal

It's common to have debcommit -r be run as part of the release process.
However, if a commit has already been made of everything in the source
tree, then debcommit makes no commit, and it seems that in this case,
it also does not make a signed tag. Result is a release with a missing
tag, which is never good. debcommit -r should always tag the most recent
commit as the release tag, unless the release tag already exists.

I have only verified this happens with git, but it seems likely to
also affect other VCS.
