possible to tweak 'f, F, t, T' so that we drop collapse selection as we move over the matches?

[effinsky]

I've been unable to do this, figured there's sth in the way of remapping these -- the first two don't collapse the selection.

"f" = ["find_next_char", "collapse_selection"]
"F" = ["find_prev_char", "collapse_selection"]
"C-f" = ["repeat_last_motion", "collapse_selection"]

Oddly enough, remapping repeat_last_motion does work as intended here. Am I missing sth? Maybe it'd be good to include these in your mappings if we could make them work.
