I think that's a feature.  Note that R CMD INSTALL on such a package
does install the package under its "real" name.

It is a feature because it allows me to distinguish the tarballs from
each other.

Perhaps you can make this work for you by using a more meaningful
description than version number in your branch name.  For example:

.../branches/foo-release
.../branches/foo-devel
.../branches/foo-someNewFeature

As another poster suggested, an SCM is the right tool for tracking
versions.
