A branch tip is analogous to a repository tip: the highest-numbered
revision in the branch. In the named-branch sphere, it's a concept
that's used enough to have its own jargon, I think, and I at least have
been using it for quite a while. And it's also a good summary of what
revision a branch name refers to in a revision context.

Meanwhile, the global tip concept has become almost meaningless. With
named branches, it's pretty much irrelevant, and without them, tip ==
default. As tip can only confuse people trying to use named branches, we
should probably start phasing it out of our vocabulary.

In newspaper style, the long form of name is given on the first mention,
and a short form in all subsequent mentions. We should do something
similar. In particular, we should probably do -r/--rev first, and then
-r everywhere after.
