clipping patch (from <Someone>)

No objections were heard to this previously circulated
change.

> Clipping should occur right before user input (rhack) vs in the
> beginning of the move loop. For example, if hero had
> "teleportitis" and teleported because of that then the clipping
> region was not updated to reflect a new hero position until the
> next turn. This patch fixes that.
