Sorry, two things here. The ^ actually should be one more space to the
right, and I was thinking about my other example. It's
arglist-cont-nonempty in this case. It's set to + too.

  arglist-intro:
  a_method(another_method(
               foo, bar));


  arglist-cont-nonempty:
  a_method(another_method(foo,
               bar));

CC Mode version 5.28

I'll check out 5.30. Indenting from the beginning of the line is the
issue I wasn't sure how to work around.

I looked at indentation functions a while ago. Rechecking now, they
take a syntactic component cons cell which contains the "buffer
relative position" and return the offset to add to that position. I'm
by no means an elisp guru, so I may be missing something, but since
it's the buffer relative position that I don't like I'm not sure how
to get that to work. It sounds like CC Mode 5.30 may help there
though.

Thanks!
