log10, was: bug report, or am I doing something wrong?

There are probably others, but here are a few of them that I know
about:

     %he[n] (z)                     Hermite polynomial (Nota bene: `he', not `h'. See A&S 22.5.18)
     hstruve[n] (z)                 Struve H function
     lstruve[n] (z)                 Struve L function
     %f[p,q] ([], [], expr)         Generalized Hypergeometric function
     gammagreek(a,z)                Incomplete gamma function
     gammaincomplete(a,z)           Tail of incomplete gamma function
     slommel
     %m[u,k] (z)                    Whittaker function, 1st kind
     %w[u,k] (z)                    Whittaker function, 2nd kind
     erfc (z)                       Complement of the erf function
     ei (z)                         Exponential integral (?)
     kelliptic (z)                  Complete elliptic integral of the first kind (K)
     %d [n] (z)                     Parabolic cylinder function

These are taken from the help for specint.  (There are many others in
the source code for specint.)  Actually, I don't think maxima can
currently evaluate any of these numerically.  What maxima knows about
these functions is very limited or non-existent.
