[PATCH] git cvsimport sanity checking

["Tommy M. McGuire" <mcguire@crsr.net>]

This patch adds some sanity checking to git-cvsimport-script,
specifically forcing the use of cvsps -x (to get the latest information
from the repository, rather than whatever is in the cache) and aborting
early if cvsps does not produce any output.

I debated removing the $MODULE directory following an abort, but I
eventually decided leaving stuff behind would make debugging easier.  On
the other hand, this patch should help with the "cvsimport left me with
an empty repository" complaints.

Signed-off-by: Tommy McGuire <mcguire@crsr.net>

Call cvsps with the -x flag, to get the current state of the repository,
and abort the cvs import early if cvsps does not produce any output.
