I wouldn't be so sure. It's possible to get files on a branch with a
"-D" argument. Sometimes, that's what you want, so you can say it "just
works", and sometimes, that's not what you want. "-D yesterday" in a
directory is usually what you want, because it's a diff against what was
there before, against what was just committed, but a whole tree with a
"-D" tag? Not useful (if it does what I think it does).

There is no such thing as "notag + date tag". Especially not, if you
want it to mean "HEAD + date". "notag + date tag" is identical to "date
tag". There's only one slot for the tag/date/branch. That's my point. I
think "-D" must simply pick through the history to get the last change
before that date, without regard to branches.
