debchange distribution default for Ubuntu broken

Binary package hint: devscripts

A recent merge broke debchange's distribution default for Ubuntu. 'dch -r' is meant to use karmic rather than the most recent distribution in the changelog; this is because, unlike Debian, uploading to "unstable" (common case where the package was synced from Debian) or "jaunty" etc. (common case where the package was last uploaded to a previous Ubuntu release) is unlikely to be correct.

The diff between 2.10.48ubuntu2 and 2.10.53ubuntu1 shows:

The "if ($distributor eq 'Ubuntu')" bit should not have been dropped, although it would make sense for the new $dist_indicator to override it.
