bug report, or am I doing something wrong?

In a rather nice paper by Margret Brown, full ref below, she suggests a
new convention for lograithms.  Her paper uses \uparrow and
\downarrow, but this can be translated into CAS syntax as follows.

a^b as ususal.

a_b will be log_a(b).

This gives, for example,

a^(a_b)= a_(a^b) = b.

Well, sometimes anyway.  Any volunteers to add this to Maxima?!
