Actually, one other idea would be to allow a numeric value for
preview-auto-reveal, and if it is set to `1', for example, open the
preview if the cursor travelled a distance of at most 1 when entering
the preview.

That would be essentially the same as the current default, except that
it would cover different distance-of-1 commands (like in viper-mode),
and that it would be quite more efficient, not requiring key lookup
(not that the situation is _that_ common or time-critical).

It would also mean, however, that commands which just _might_ end up
on the second or last char of a preview by accident, will cause the
preview to open.

What do people think? Worth an option?
