Remove universal repeater on ; and ,
Remove universal repeater on ; and ,

Ultimately, I didn't find this useful. Unifying n/N and ;/, was
inconvenient when you wanted to repeat each kind of search
independently (which happened more often than I had anticipated).

What's more, it introduced another point of confusion for new users
coming from vim. In the end, it's simply better to do as vim does.

Fixes #3689
