lib.version.Dependency.__version_boundaries(): Expand non-full specs

Full version dependency specs ("= 1.2.3-4" or "= VERSION-REVISION") don't
need expansion, they pin the wanted version with an = fine exactly.

__version_boundary has that the wrong way around, fix that.

Also fix the is_full and version_boundaries() docstrings, which still
describe the old behavior.
