git-svn: --follow-parent works with svn-remotes multiple branches
Bugs fixed: * We didn't allow manually (not using git-svn) init-ed remotes/fetch refspecs to be used before. It works now because that's what I did in this test. git-svn init should offer more control in the future. * correctly strip paths in the delta editor when using do_switch(). * Make the -i / GIT_SVN_ID option work correctly when doing fetch on a multi-ref svn-remote Signed-off-by: Eric Wong <normalperson@yhbt.net>
