Re: hs-hide-block-behavior

Fine, since the value name is not correct, the solution for me would be
to rename 'after-cursor' to 'after-point', since 31.1 is not released
yet, i don't know if it is too late to remove 'after-cursor'.

OTOH, my other solution would be to use another term than
'after-cursor', since that value is only for backward compatibility for
hideshow commands.
