PR #862 - try XLII

Browse Source 
When strength loss is so big as to cause HP damage, but reduce
strength if the damage causes hero to revert to normal form.  There's
no point in adjusting strength before rehumanization and not fair to
do so afterward.

Also, validate strength and its intended adjustment before doing
anything else.  (Just paranoia; there's no reason to suspect that any
bad data ever gets passed in.)
