branch doc: update description for --list

The paragraph begins with a sample command line `git branch <name>`
that has nothing to do with the option being described.  Remove it,
but use the space to instead show that multiple patterns can be
given.

Also mention the unfortunate `-l` that can be easily confused with
it.
