Where has "git ls-remote" reference pattern matching gone?

git-ls-remote(1) says that ls-remote supports filtering by reference  
name:

SYNOPSIS
       git-ls-remote [--heads] [--tags]  [-u <exec> | --upload-pack  
<exec>]
                     <repository> <refs>...

[...]

       <refs>...
              When unspecified, all references, after filtering done  
with
              --heads and --tags, are shown. When <refs>... are  
specified,
              only references matching the given patterns are  
displayed.

[...]

       $ git ls-remote --tags public v\*
       d6602ec5194c87b0fc87103ca4d67251c76f233a        refs/tags/v0.99
       f25a265a342aed6041ab0cc484224d9ca54b6f41        refs/tags/ 
v0.99.1
       c5db5456ae3b0873fc659c19fafdde22313cc441        refs/tags/ 
v0.99.2
       7ceca275d047c90c0c7d5afb13ab97efdf51bd6e        refs/tags/ 
v0.99.3

But when I try to use the <refs> argument on a current build of git  
(git version v1.5.3.7-1112-g9758ecd), I just get its usage message,  
which doesn't mention that argument:

vredefort:[backup]% git ls-remote origin foob
usage: git-ls-remote [--upload-pack=<git-upload-pack>]  
[<host>:]<directory>

ls-remote was recently made a builtin; was reference filtering  
deliberately removed, or was it just lost in translation from the  
shell script?
