It's not just '--edit-description', most other options won't accept
multiple branches either.  As far as I can tell only deleting branches
can deal with multiple branches in one go.

Furthermore, branch descriptions are likely more lines long, so we
can't just dump them one after the other, but we we would have to
separate the descriptions of different branches in the output.
Considering that 'git branch' mostly works only with a single branch at
a time, I didn't feel the need to do so.
