Removing the penalty for breaking after "=".

Having seen more cases, this actually was not a good thing to do in the
first place. We can still improve on what we do now, but breaking after
the "=" is good in many cases.

Before:
aaaaaaaaaaaaa = aa->aaaaaaaaaaaaaaaaaaaa(
                    aaaaaaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaa));

After:
aaaaaaaaaaaaa =
    aa->aaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaaaaaaaaaaaa(aaaaaaaaaaaaaa));
