Move Text Undo Behavior

[sbdchd]

Currently, when moving text via move-text-micro-state, each movement in the micro state is added to the undo history.

This means that if I were to hit K 5 times to move a block of text up, I would then have to undo 5 times, instead of just one.

I've reproduced this problem as well.
