[PATCH][resend] git-svn: Respect GIT_SSH setting

[Karthik R <karthikr@fastmail.fm>]

Setting GIT_SSH when using "git svn clone svn+ssh://..." does not
override the default ssh; SVN_SSH needed to be set instead. Fixed
this.

Also, on Windows, SVN_SSH needs to be set with \ escaped
  e.g., "C:\\PuTTY\\plink.exe"

See http://code.google.com/p/msysgit/issues/detail?id=305
