Would you mind splitting up this patch so that the
completion part is done separately?

It'd probably be better to use test_expect_code instead of
test_must_fail here:

	test_expect_code 1 git merge master ...

I realize that this test is based on an existing one, but I'm curious..
is "yes" used above because it's prompting, and using -y or --no-prompt
here would eliminate the need for the 'yes ""' parts?

Looks good otherwise.
