OK, I misread the patch assuming that opt_rebase was only reflecting the
options, but it is also set by the config:

	if (opt_rebase < 0)
		opt_rebase = config_get_rebase();

... or just "when pull is used in rebase mode", which is shorter and
still technically accurate. I don't think you need to be exhaustive in
this kind of documentation, the user will notice anyway if he tries to
use --autostash in a forbidden situation.

I'd rather have something technically correct.

I think you should also change one of the tests to use pull.resbase=true
so that this behavior is properly tested.
