Honestly, I'd never guess it'd "delete the last branch". No way.

"-" standing by itself in a command means stdin, stdout, or otherwise a
typo. Using it for any other meaning is a blasphemy. Sure, nobody will
die because of this, but it's /extremely/ confusing!

BTW, what about mistyping:

$ git branch -d - f my_branch

for

$ git branch -d -f my_branch

or some such?

No, it still doesn't look like a good idea to use isolated '-' as
suggested by the patch.

OTOH, for otherwise unusual @{-1}, @{-}, or @- I'd immediately realize I
must consult the manual, so these would be fine with me.

Thanks,
