git-svn usability

I wanted to try out "git svn" and did a "git help svn" and got the man page for git-svn. That page starts out by describing that git-svn only is useful for working with a single svn branch. But then, further down, it describes the commands "multi-init" and "multi-fetch" anyway. Confusing. But I decided to give them a try. But there isn't really any clear description on what the command line should look like when you use multi-init (or any other git-svn command for that matter). So I boldly decided to try to run "git svn help multi-init". You never know, it might tell you something. This is what happened:

  morpheus% git svn help multi-init
  GIT_SVN_ID set to 'trunk' for help/trunk
  Initialized empty Git repository in /home/david/tmp/.git/
  W: --branches/-b not specified
  W: --tags/-t not specified

Not exactly what I wanted. The command-line parser in git-svn is broken since it picks the first argument that looks like a command name.
