Thanks a lot, that clarifies the problem for me. As far as I understand now:

1) I can't have just one .gitignore file in the root dir, if I want to 
_recursively_ inverse the exclude pattern for a sub dir tree.
In this case, I have to put individual .gitignore files in the sub trees 
I want to re-include.

2) In order to see what will be staged, I have to use the :
git ls-files -o --exclude-standard
instead of :
git ls-files -o -i --exclude-from=.gitignore
because the latter won't consider .gitignore patterns in subtree
