That is also my thinking.  But perhaps we can leave a flag around to
enable getting Whittaker M functions.

And if you're working on Kummer M, then I can have it convert 1F1 to
kummer_m.  Or maybe we should follow Mathematica and use
hypergeometric_1f1 here.  (It currently does %f[a,b](x).)  Or
something else.
