renaming. If <newbranch> exists, -M must be used to force the rename
to happen.
+The `-c` and `-C` options have the exact same semantics as `-m` and
+`-M`, except instead of the branch being renamed it along with its
+config and reflog will be copied to a new name.
+
With a `-d` or `-D` option, `<branchname>` will be deleted. You may
specify more than one branch for deletion. If the branch currently
has a reflog then the reflog will also be deleted.
In combination with `-d` (or `--delete`), allow deleting the
branch irrespective of its merged status. In combination with
`-m` (or `--move`), allow renaming the branch even if the new
- branch name already exists.
+ branch name already exists, the same applies for `-c` (or `--copy`).
