HELP RECURSIVE_FRONT               updated Mark Rubinstein  November 1985

    recursive_front(<item>) -> item

If the argument is not a pair, the argument is returned. Otherwise
RECURSIVE_FRONT is applied to the *FRONT of the item.

This procedure is used by *SYSPR in printing the names of procedures.
SYSPR takes the *PDPROPS of the procedure and if that is a list (i.e. a
pair) takes its front, and continues until it gets something which is not
a list. Usually this will be a word.  This enables the *PDPROPS of a
procedure to be used to associate a list of information with the
procedure, starting with the name, or starting with something which
includes the name.
