Eh, which one?  I do not recall ever doing so, but I may be
mistaken.

"git show v0.99.1" gives both tag object contents *and* the output
from "git show v0.99.1^0" for the commit, so it is possible that I
never did so, but those who ask "git show" may get such an
impression?

I think #3 is a show-stopper.

We will keep the RelNotes file updated with every batch that updates
the 'master' front, so the contents of that imaginary tag that has
the copy of the release notes would become identical to the in-tree
blob at the point of a release.  There has to be a very good reason
why it is beneficial to _duplicate_ the information, not the other
way around to ask why we do not duplicate the information in
different places, I think.
