fix(repeatable_move): handle *forced-motion* v

[illia-shkroba]

this one is for handling forced-motion (:h forced-motion) with ; / , motions
sometimes I do dv; and I expect the ; to be exclusive rather than inclusive
for example, for the text like /var/cache/pacman/pkg:

0f/dv;

should drop the /cache from the text so the remaining text would be /var/pacman/pkg

currently (without this PR change) the result would be /varpacman/pkg for the same sequence

I've added the respective tests as well

please check kindly

Hi @kiyoon
could you please take a look in your free time?
