The git-cvsimport-script had a copule of small bugs that prevented me from importing a big CVS repository. The first was that it didn't handle removed files with a multi-digit primary revision number. The second was that it was asking the CVS server for "F" messages, although they were not handled. I also updated the documentation for that script to correspond to actual flags. Signed-off-by: David Kågedal <davidk@lysator.liu.se>
