V-HANG-UP does not clear WEARBIT

[eriktorbjorn]

>INVENTORY
You are carrying:
  a costume receipt
  a western mask (being worn)
  a notebook
  a pen
  a gunbelt (being worn)

>HANG UP GUNBELT
Hung.

>LOOK
East Coat Closet
This is a large coat closet full of rather damp coats, overcoats, and raincoats.
There's a gunbelt here.
There's a reporter's overcoat here.

>TAKE OFF GUNBELT
Okay, you're no longer wearing the gunbelt.

That's because V-HANG-UP moves the object from your inventory into the room, but does not clear its WEARBIT in the process:

			     (T
			      <MOVE ,PRSO ,HERE>
			      <TELL "Hung." CR>)>)

Another thing that doesn't clear WEARBIT is showing objects to the detective. See DETECTIVE-F:

		      (<VERB? SHOW>
		       <MOVE ,PRSO ,DETECTIVE>
		       <FSET ,PRSO ,TRYTAKEBIT>
		       <TELL
" looks at " THE ,PRSO " for a moment, then takes it.">)

>INVENTORY
You are carrying:
  a costume receipt
  a western mask (being worn)
  a notebook
  a pen
  a gunbelt (being worn)

>SHOW WESTERN MASK TO DETECTIVE
The detective looks at the western mask for a moment, then takes it. "Well,
thank you, but I don't see what this has to do with the case."

>FIND WESTERN MASK
The detective has it.

>TAKE OFF WESTERN MASK
You remove your mask, revealing your smiling face and twinkling eyes.
