 -With the `--branch` option, it expands a branch name shorthand and
 -prints the name of the branch the shorthand refers to.
+ 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.
