You might doubt it, but having written the code I can tell you that it's the
case. Shame on me for not writing a test, though.
I see the argument why this indentation is not necessary in exactly the case
where the last parameter is multi-line and not wrapped to a new line itself:
You always have some indentation anyway because of the preceding parameter on
the same line.
However, for me the consistency is more important here, i.e. achieving that we
don't have a relative indentation change between:
foo(a, bbbbbbbbbbbbbbbbbb +
ccccccccccccccccc);
and
foo(a,
bbbbbbbbbbbbbbbbbb +
ccccccccccccccccc);
This formatting can easily alter between these two when line length vary
slightly and I think being able to pattern match that easily.
Yes, that means it is not consistent with:
foo(bbbbbbbbbbbbbbbbbb +
ccccccccccccccccc);
But there is actually a substantial difference in structure and so, I think it
is reasonable to not be consistent there.
