next_ocur does not work

Created by: ducks

Reproduction: enter insert mode. type "this is some zest". use shift+space to drop back into normal mode. use gg to go back to the start of the line. use "tz" to find the z in zest.

Expected behavior: cursor goes to the z in zest

Actual behavior: cursor stays at the beginning of the line

This issue seems to be caused by this line: https://github.com/redox-os/sodium/blob/master/src/caret/movement.rs#L146

I tried printing out the n and dn and it seems like the n always came in as 1 and the dn is set at 0 so that if would never fire. I tried multiple lines and n still seemed to be 1.

I see that n is set here: https://github.com/redox-os/sodium/blob/master/src/core/exec.rs#L18 but have not tracked down where that comes from and what it does just yet.

next_ocur() also seems to just return the x that was passed to it: https://github.com/redox-os/sodium/blob/master/src/caret/movement.rs#L150
