2*a*2^k isn't simplified. But a*2^k*2 is. There are
many other situations where we don't simplify such
products.

    Observed in 5.9.3.99rc2. Looks like this is happening (or
    not happening) in SIMPTIMES.

    With revision 1.80 of simp.lisp the example simplifies as expected:

    (%i1) 2*a*2^k;
    (%o1) a*2^(k+1)

    Closing this bug report as fixed.
