Maybe it's possible to do that for dependencies, but VDB entries and
binary packages for above two examples would still collide.
So the conclusion still stands:

Hyphens within PV are a Bad Thing, and we should really think about
replacing the separator for "scm" by something else, like a period or
an underscore. For example, the following two would be unique:
${PORTDIR}/app-misc/foo/foo-1a_live.ebuild
${PORTDIR}/app-misc/foo-1a/foo-1a-live.ebuild
With our current versioning scheme the rule is very simple: ${P} is
split into ${PN} and ${PV} at the last hyphen. This can be done in a
straight forward way by regexp matching, and I would really hate to
lose this nice property.
