c-context-line-break doesn't really have much to say in the matter.  The
function is mainly about how to indent the _new_ line, and inserting
various continuation markers.

This bug is about trailing space in the _old_ line not getting removed
on typing <CR>, about which c-context-line-break has nothing to say.
