'git check-ref-format' <refname>
+'git check-ref-format' --print <refname>
'git check-ref-format' --branch <branchname-shorthand>
DESCRIPTION
. at-open-brace `@{` is used as a notation to access a reflog entry.
+With the `--print` option, if 'refname' is acceptable, it prints the
+canonicalized name of a hypothetical reference with that name. That is,
+it prints 'refname' with any extra `/` characters removed.
+
With the `--branch` option, it expands the ``previous branch syntax''
`@{-n}`. For example, `@{-1}` is a way to refer the last branch you
were on. This option should be used by porcelains to accept this
syntax anywhere a branch name is expected, so they can act as if you
typed the branch name.
-EXAMPLE
--------
-
-git check-ref-format --branch @{-1}::
-
-Print the name of the previous branch.
