Would it be possible to have "wimpy dir auto", where it would set your wimpy
dir at each more to the opposite direction of the move.

In most cases, this would nicely let you automatically wimpy to where you came
from. Perhaps do not set the new direction if movement is wimpying to prevent
wimpy balling between monsters.
