bug#57669: 29.0.50; C-n, C-p off under long lines

No problem?  None?  The fortune you could have made had you pursued a
career in corporate messaging.

In all the reams of tail-chasing in Bug#56682 and Bug#56393, I managed
to locate just one preemptive mention by the proposer:

  This feature comes at a (IMO) very little price, namely...
  point sometimes moves to another column...

He is careful to minimize the issue, but he doesn't say "I see no
problem with that."

Emacs devs are fascinating.  Even with no money or fame at stake, guys
choose the weirdest hills to die on.  One guy repudiated the long lines
fix over some cc-mode regression.  Another for imperfectly colorizing
json.  Another for circumstantially forbidding "widen".  But none of
them appeared to care the slightest about something as basic as "C-n"
and "C-p".  A "very little price" indeed.
