commit 59f0c7e15b69651271e8b9b94d8169eddd4ba9df

Correct comments regarding simplified arguments for ADDK and TIMESK
The original comments for the functions ADDK and TIMESK stated that
"The arguments must not be simplified." This was likely a translation error
(a false friend from the German "müssen nicht"), meaning the arguments
"need not be simplified."
However, the code actually expects the arguments to be simplified (reduced, in
the case of Maxima rationals). Passing in unreduced rationals can result in
unreduced results or even errors, for example:
:lisp (TIMESK '((RAT) 4 -2) 1)
((RAT) 4 -2)
:lisp (ADDK '((BIGFLOAT SIMP 56) 1 1) '((RAT) 1 -1))
Maxima encountered a Lisp error:
The assertion (> EXTRA 1) failed with EXTRA = 0.
