Removed extranous/added missing food intolerance warnings. Added missing morale penalty to wheat intolerance.
Enable curing status-damage on full-HP limbs

Ain't pretty but it works.  (Took a while to actually get a Deep Bite.
Apologies for the delay.)
Side fix

Noticed that Masochist didn't change_to Pain Junkie.  Since the point of
PJ is that it isn't capped like Masochist, fixed the problem.
That arm is broken.  But status-fixes aren't.

It won't raise its HP any, but it can fix the status.
Legs too!

Hate it when that happens!
