Hmm, I am having another problem with git-svn going back and download
everything over and over with this:

git svn clone -s https://ndiswrapper.svn.sourceforge.net/svnroot/ndiswrapper

I am going to do two-step init -s then fetch --all now to see if it helps.

(it is probably not entirely standard layout with the extra CVSROOT?)
