Patch Level: 0
Release Status: release


Description:

`hash -d NAME' does not remove NAME from the command hash table.


Repeat-By:

hash -r
type find
  -> find is /usr/bin/find
hash find
type find
  -> find is hashed (/usr/bin/find)
hash -d find
type find
  -> find is hashed (/usr/bin/find)


Fix:

At present, after `hash_builtin' successfully removes an element, it
immediately adds it back again. Possible patch:
