From a bug report: dwarvish mattock was
subject to breaking when attempting to force a lock, because it is treated
as a bladed weapon. So is pick-axe; they're both defined as blunt (WHACK
attack mode), but the definition of is_blade() erroneously includes them
since P_PICK_AXE falls between P_DAGGER and P_SABER. That skill should be
renumbered, but I haven't investigated what else might happen when that's
done so this fix uses a special case instead.
I noticed that there was an unnecessary old check for rubber hose;
it's excluded along with whip by the skill > P_LANCE test. When fixing
that up, I realized that the obscure feature of forcing via statue was
broken; it always failed the skill < P_DAGGER test. Also, I took away the
exception for aklys; even though designed as a throwing weapon, it is used
as a club. I wasn't sure about the exception for flail; it is perfectly
capable of bashing things but the code apparently excludes it for use as
a prying implement. Switching its check to P_FLAIL catches grappling hook
along with it.
