dch -r should detect when update-maintainer needs to be run

[Steve Langasek]

When making first modifications to a package on the UDD branch, I frequently get caught out by not having run 'update-maintainer' until I get to the point of running 'bzr bd -S'. I frequently don't build the source package until *after* I've finished developing and have already pushed the branch to launchpad... complete with a release tag on the wrong revision, because I then have to update the branch again with the result of update-maintainer.

Catching update-maintainer at the source building stage isn't a problem for classic workflows, but for UDD, where I'll have already committed the change to bzr, it can be a real pain. I think either 'dch -r' or 'debcommit -r' should catch the fact that update-maintainer hasn't been run yet, and abort with the same error that dpkg-buildpackage outputs.
