Weening> Emacs 18.55, Sun OS 4.0.3.  In C mode, code such as the following
Weening> doesn't indent correctly:

Weening> main() {
Weening>   while (1) {
Weening>     x = 1;
Weening> #define foo (a+\
Weening> 	     b)
Weening>   y = 2;

Weening> After the continuation line of the #define, Emacs indents two
Weening> columns instead of four as needed in this context.

c-backward-to-noncomment doesn't handle continuation lines properly.
Here's the fix:
