 dereferenced into object IDs. Additionally, it can be used to test whether a
 particular ref exists.
 
+The --exclude-existing form is a filter that does the inverse, it shows the
+refs from stdin that don't exist in the local repository.

 Use of this utility is encouraged in favor of directly accessing files under
 in the `.git` directory.
 
 OPTIONS
 -------
 
--h, --head::
+-h::
+--head::
 
        Show the HEAD reference.
 
---tags, --heads::
+--tags::
+--heads::
 
        Limit to only "refs/heads" and "refs/tags", respectively.  These
        options are not mutually exclusive; when given both, references stored
        in "refs/heads" and "refs/tags" are displayed.
 
--d, --dereference::
+-d::
+--dereference::
 
        Dereference tags into object IDs as well. They will be shown with "^{}"
        appended.
 
--s, --hash::
+-s::
+--hash::
 
        Only show the SHA1 hash, not the reference name. When also using
        --dereference the dereferenced tag will still be shown after the SHA1.

+--abbrev=len::
 
        Abbreviate the object name.  When using `--hash`, you do
        not have to say `--hash --abbrev`; `--hash=len` would do.
 
--q, --quiet::
+-q::
+--quiet::
 
        Do not print any results to stdout. When combined with '--verify' this
        can be used to silently check if a reference exists.
