Don't try to do a hanging ident after assignments.

Before:
bool aaaa = aaaaaaaaaaa(
                aaaaaaaaaaaaaaaaa);

After:
bool aaaa = aaaaaaaaaaa(
    aaaaaaaaaaaaaaaaa);

The other indentation was a nice attempt but doesn't work in many cases.
Not sure what the right long term solution is as the "After: " is still
not nice. We either need to figure out what to do in the cases where it
"doesn't work" or come up with a third solution, e.g. falling back to:

bool aaaa =
    aaaaaaaaaaa(
        aaaaaaaaaaaaaaaaa);

which should always work and nicely highlight the structure.
