Re: C-n and C-a

    If the only use of visual-line-mode without word-wrap is
    programmatically (by other modes), then maybe it's enough to just force
    word-wrap off in those modes somehow (either by frobbing the variable
    itself after turning it on, or by some let-binding around the mode
    invocation).

The cleanest way would be to have a variable that these modes can set,
which causes Visual-Line mode not to enable word wrap by default.
