Bug: git ls-files and ignored directories

@Jeff: Thank you for the clarification. I didn't want to appear pushy, I 
just wanted to make sure that I did everything right and that my mail 
won't get ignored/filtered because of some breach of protocol.

@Junio, Duy: Thanks for starting/proposing work on this!

thanks,
Christoph

No, I don't think anybody is working on it at the moment (at least I
do not see anything near the time of that old discussion, nor do I
recall it being discussed since).

+cc Clemens, in case he had any work-in-progress as a result that did
not end up getting published.

I think the way the codepath for -i feeds path to excluded() is wrong.

The excluded() interface relies on the fact that the caller has
already checked foo/ before calling it for foo/bar; when asked to
see if "foo/bar" is excluded, it does not consider if "foo/" is
excluded---the caller should have already checked it.

Sparse checkout deals with the exact same problem and it reconstructs
a tree structure from cache list, before feeding to excluded(). I
thought of generalizing it (e.g. for this case), but with v5 in
progress, we'll probably have tree-based index soon. "ls-files -i"
could be fixed by then.
