 . at-open-brace `@{` is used as a notation to access a reflog entry.

+With the `--print` option, if 'refname' is acceptable, it prints the

+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.
