[PATCH] Also handle CVS branches with a '/' in their name

I track a CVS project which has a branch with a '/' in the branch name.
Since git wants the branch name to be a file name at the same time,
substitute that character to a '-' by default (override with "-s <subst>").
This should work well, despite the fact that a division and a difference
are completely different :-)
