I can't find the discussion right now, but I have a recollection that
"git branch -D -" was explicitly rejected when "-" was being added as
an alias for @{-1} to other modes and other commands. The reason for
the rejection was that branch deletion is a destructive operation (the
ref-log, in particular, is gone after deletion), and "-" alone
provides no clues and no context that you're deleting the branch you
intend to delete. (The lack of clues and context isn't a big deal for
non-destructive commands, such as git-switch.)
