This line is broken and it is carried over to later patches. It
needs to be -Xours (or --strategy-option=ours, if we really want ot
be verbose).

I was hesitant to hardcode what I perceive as limitations of non-am
rebase implementations with a test like this, but once somebody
fixes "rebase -i" for example to be capable of --whitespace=fix for
example, then we can just drop one line from the above four (and
write other tests for "rebase -i --whitespace=fix"). The
test_rebase_am_only is to help us make sure what is (still) not
supported by non-am rebases gets diagnosed as an error.
So my worry is totally unfounded, which is good.
