How does it reduce the information we give? Maybe I've missed
something about what "from" means here, as opposed to "at", but it
seems to me to mean the same thing as "diverged" by definition, i.e.
we detached from the branch but we diverged from it. Saying "diverged"
just makes it clearer, how does it reduce the information we give?

> Note that the difference between from and at is also: are there commits that we could lose when we switch away, that is: that git checkout would warn us about?

Right, but I don't see how that's in any way conflicting or mutually
exclusive with saying before hand that we've diverged from the branch.

Aside from whether my patch makes any sense, the solution to a UX
issue really can't be "oh this just needs to be documented". For every
user who's confused by some interface we provide a *tiny* minority of
them go and exhaustively read the docs for an explanation, will just
remain confused.

I think saying from v.s. at is way too subtle, I for one have been
missing it for years until this thread, that's bad UX, git's also used
by a lot of non-native English speakers who may not at all get the
subtle difference between at and from in this context, or if they do
think the UI is using that subtlety to tell them something.
