How do I get Maxima to automatically use
the tellsimpafter rules until no further change
occurs in the expression?

Closer reading of the help manual suggests
the strategy:

(%i17) expand (ev (comm(a^^3,c),infeval));
(%o17) comm(a,c) . a^^2+a^^2 . comm(a,c)+a . comm(a,c) . a

(%i18) expand (ev (comm(a^^4,c),infeval));
(%o18) comm(a,c) . a^^3+a^^3 . comm(a,c)+a^^2 . comm(a,c) . a
                       +a . comm(a,c) . a^^2
