Over-sensitive directional tag detection

[Cobra]

When reversing a way tagged type=drawdown josm shows the automatic tag correction dialog proposing to change type=drawdown into type=drawup, which is complete nonsense.

I did not yet find any other false detections during editing, but I can provoke some quite stupid proposals. Name=* is ignored, but any other tags containing "up" or "down" will get caught, including ref=*.
Bad proposals:

• drawdown -> drawup (wat)
• uptown/downtown
• upper -> downper (ouch!)
• I'm sure there are some more I can't think of now.

I don't think this is a frequent problem, but I feel like the detection needs to be a little bit smarter. Maybe checking against a list of known "bad" words could be start.
