see line "index 722c620..6abb687 100644". What does this mean ?
'722c620' is the commit id in which a/exec.h is part of and
'6abb687' is the commit id in which b/exec.h is part of. 'a' and 'b' are not folders. Its just a notation that diff uses for left and right side.
to know more on git look here: http://git-scm.com/book
and git diff in particular look at the man page or search for "git diff" and you get a lot of links that explains it...
