As good as the content based rename detection is I got burned
recently by it.

I renamed hundreds of small files in one shot and also did a few
hundered adds and deletes of other small XML files.  Git generated
a lot of those unrelated adds/deletes as rename/modifies, as their
content was very similiar.  Some people involved in the project
freaked as the files actually had nothing in common with one
another... except for a lot of XML elements (as they shared the
same DTD).
