Surely the name explains it. :)

GNU make, unlike, say, pmake, reads all the rules before it runs
anything iirc.  So you can have

 -include foo

 foo:
	echo bar: >foo
	echo '	echo hi' >>foo

and it will cope okay.

Anyway, the git makefile is very far from topologically sorted; if
you are suggesting we change that, that's fine with me, as long as
the new rule is somehow justified and consistent.

Hope that helps,
Jonathan
