All right, then. But are they used often?

Branches are a well-used feature in Git. If the majority of users of a 
different VCS X are not aware of branches, and don't use them, showing 
the current branch everywhere might not be very useful.

'git describe' output can be fairly long (e.g. 1.11.0-55-gegegege), and, 
for one, I'm not very comfortable with it (how useful exactly is it to 
know that the branch is XY commits ahead of the latest tag?).

Maybe we should make a poll.
