Shouldn't this error out with a clean error message ("branch name
expected" or so)?

Yeah. But on the other hand, this command seems to prefer to print
help usage when incorrect number of arguments is given (checkout
blocks "if (edit_description)" and "if (rename)" in cmd_branch).
Should those be fixed too?

Good catch.  Shouldn't this bugfix be a separate patch, so it can also
be included in maint?

This worried me for a second --- is it an actual message that gets
emitted, a placeholder used only in code, or some combination of
the two?

Luckily it really is just a message (or rather, a value for the commit
message column in the " f7c0c00 [ahead 58, behind 197] vcs-svn: drop
obj_pool.h" message).

For what it's worth, assuming this passes tests,

Forgot to sign-off?

Is this a real problem?

I do not see it particularly wrong to succeed after deleting 0 or
more given branch names.

Yes

> Is this a real problem?

Yes. My thoughts yesterday when I happened to type "git branch -D":

"Wait, I just entered a delete command without a branch name. It did
not report anything, which in UNIX world usually means successful
operation. _What_ did it delete??"

I knew this code so I just went check. If I did not know, I might as
well list all branches I had and see if something was missing. A short
message would have saved me the trouble.
