cvsimport: honor -i and non -i upon subsequent imports
Documentation says -i is "import only", so without it, subsequent import should update the current branch and working tree files in a sensible way. "A sensible way" defined by this commit is "act as if it is a git pull from foreign repository which happens to be CVS not git". So: - If importing into the current branch (note that cvsimport requires the tracking branch is pristine -- you checked out the tracking branch but it is your responsibility not to make your own commits there), fast forward the branch head and match the index and working tree using two-way merge, just like "git pull" does. - If importing into a separate tracking branch, update that branch head, and merge it into your current branch, again, just like "git pull" does.
