I've come across this too.  Personally I'm not sure what use "-C" is.  From 
the manpage, man git-diff-files (no, this isn't the place I'd look either).

The real issue here is because the b/a on the command line
applies on the input-side, and does not act as the output
filter.  This comes from _very_ early design decision and if you
dig the list archive you will see Linus and I arguing about
diffcore-pathspec (which later died off).

What it means is that "git log" will look at path that matches
b/a (that means b/a/c and b/a/d are looked at, if b/a were a
directory).  Since path "a" which is what the file was
originally at is not something the pattern b/a matches, there is
no way b/a is noticed as a rename from a.

I've been meaning to resurrect Fredrik's --single-follow=path
patch but haven't had time to recently, with all the other
interesting discussion happening on the list.
