(remove-nth-alias append)

General Form: (remove-nth-alias alias-name)

See nth-aliases-table for further discussion; also see add-nth-alias. This form sets nth-aliases-table to the result of deleting the key alias-name from that table. If the name does not occur in the table, then this form still generates an event, but the event has no real effect.
