As promised in 0fa2eb530fb7 (add: warn when -u or -A is used without
pathspec, 2013-01-28), "git add -u/-A" that is run without pathspec
in a subdirectory will stop working sometime before Git 2.0, to wean
users off of the old default, in preparation for adopting the new
default in Git 2.0.
I originally thought this step was necessary, but I changed my mind. The
warning is big enough and doesn't need to be turned into an error.
If this step is applied, it should be applied at 2.0, not before, as
this is the big incompatible change. Re-introducing a new behavior won't
harm users OTOH.
