bug#4828: 23.1.50; c-newline-and-indent and indent-line-function

c-newline-and-indent calls indent-according-to-mode to get indentation
right for a major mode. However in the case of multiple major modes in a
buffer (not yet part of Emacs) the current major mode is not enough to
know to get the indentation correct.

MuMaMo (a framework for multiple major modes in a buffer) therefore
instead sets indent-line-function which is more flexible. However when
the user uses c-electric-semi&comma this is bypassed since this
function calls c-newline-and-indent.

I just got a bug report where this problem shows up:

I do not know how to solve this problem, but perhaps is it possible that
c-newline-and-indent instead calls indent-line-function?
