The fact that the repo is stored in .git is an implementation detail - and one which git-status knows about (in the normal case).

In the gidir: case one part of git status understands the details (after all - it reads real-git-dir/index) while another part doesn't (after all - it show the actual repo as a normal directory).

Sure, git-real-dir could be added to git-real-dir/info/exclude. But by that logic we could insist on adding .git to .git/info/exclude.

The argument about an unrelated repo in the working tree is irrelevant - .git wouldn't point to it, so there's nothings special about it.

But it's obviously not a big deal either way and I'm gonna drop it.
