Linebreaks in cpfuncs

[jcoo092]

Somewhat related to #5 but not quite the same. The solution to #3, introduced by the pull request #14, breaks the capability of performing line breaks inside cpfunc macros. You can include newline and linebreak macros inside cpfuncs, but the latter macros seem to be ignored, best as I can tell. Using \\ causes compilation errors.

I'm not sure what the solution is, but it would be good to re-enable the capability since sometimes there isn't really anything for it but to break a cpfunc across multiple lines.
