I think this v2 should address the comments Jeff King had in

there's now an amended version of his proposed patch as part of this,
but I prepended it with another one to prepare the "struct
child_process" in cmd_difftool().

Doing so nicely gets around the question of the strvec memory
management, since we can trust the run-command.c API to do that for
us, but couldn't in my v1 when we'd copy our own "struct strvec *" to
its "args".

Thanks for taking my suggestions into account. I like this approach, and
I don't see any bugs. I replied separately to patch 3 with some further
opportunities for cleanup, but with or without them, this is all a
strict improvement.
