Any of them will do, because the revision (and hence the tag) determines
the complete state of the source tree.

Plus the complete VC history that precedes that revision. So if the
emacs-24 branch were magically lost, it could be partially recovered (VC
history included) from any other branch that contains a merged revision
that comes from emacs-24. (Partially means "except the revisions
committed after the emacs-24 revision you have at hand.")
