[PATCH] git svn: should not display zombie externals

["Eddy Petrișor" <eddy.petrisor@gmail.com>]

during the history of a repo a svn:external could be added and later
removed; such externals shouldn't be displayed since only the current
state is relevant

I have encountered the broken behaviour on a git-svn repo with the svn
origin a repo served via https (git 1:1.5.6-1~bpo40+1 from Debian Etch
backports.) I hope this bug doesn't have to do with the svn repo being
served via https.
