Definate bug in complr

[Robert W. Kerns <RWK at MIT-MC>]

See RWK;HARRIS BUG.  As you can see, she is defining a function SORT of one
argument.  Despite this conflict with LISP's SORT function, COMPLR fails to
do give the right error message (claims 'has been used before with the wrong
number of arguments', instead of 'redefining system function') and it
then ignores the ARGS-INFO property in favor of the FUNTYPE property, thus
leading it to breakpoint complaining of the wrong-number of arguments when it
finally IS used.

I have suggested to HARRIS that she call her function something else.
