This patch adds support -d/--dry-run option for branch(es) deletion.
If -d/--dry-run option passed to git branch -d branch..., branch(es)
will not be removed, instead just print list of branches that are
to be removed.
For example:
$ git branch
a
b
c
* master
$ git branch -d -n a b c
delete branch 'a' (261c0d1)
delete branch 'b' (261c0d1)
delete branch 'c' (261c0d1)
