I was a bit trigger happy posting this, after digging a bit more this is 
a way more serious than I originally thought.

This can be any file, including those commonly excluded such as *~.

Demonstrating this in a way that looks a lot more likely use case which 
will potentially wipe out lots of uncommitted work:

# git init -q foo && cd foo
# git init -q bar && cd bar
# touch bar bar~
# git add bar && git commit -qm asd && cd ..
# git clean -e \*~ -dn
Would remove bar/bar

If there were more tracked files in nested repo they'd be removed as 
well as long as there is at least one excluded file in nested repo.
