Between these two:

	git -c diff.ignoresubmodules=all diff
	git diff --ignore-submodules=all

one difference is that the latter disables reading extra config from
.gitmodules (!) while the former makes the command honor it.

This comes from aee9c7d6 ("Submodules: Add the new "ignore" config
option for diff and status", 2010-08-06), which is ancient and
predates even v2.0, so if you see problems with v2.12 or v2.11 but
not with older ones, that would rule out this theory.
