Request for git-svn man page

Please add instructions to the git-svn man page concerning cloning a SVN 
repositiory through a proxy. In particular make clear that also the SVN 
software has to be configured to use the proxy. See e.g. 
http://stackoverflow.com/questions/9057111/git-svn-ignores-http-proxy-debian.

I'd prepare a patch, but I have no clue about SVN, so I'm probably not 
the best choice for writing a SVN related manual. ;)

Kind regards,
  - lars.
