It does exercise; no need for "tries to" ;-).

Unless there is a compelling reason otherwise, I'd prefer tests
with a test vector like this to be spelled like this:

	diff -u result.1 file

That is, compare to show the difference actual output might have
from the expected result.  It's easier to spot the difference
when you later break things this way.

We might also want to test:

 - the index is merged;

 - the working tree matches the index;

 - the merge message (e.g. "git show -s --pretty=format:%s
   HEAD") is as expected;

Otherwise I think it is a good idea to add these tests.

By the way, I think squash_message() leaves a wrong message
template for an Octopus, which might be worth fixing.
