Consolidation is good, so long as we're assured that the definition
of the base-64 method being used in the two cases is the same.
I think there's more than one alphabet in common use, for different
purposes... But if this turns out to be the case, perhaps a merged
routine could handle either.

Some microbenchmarking wouldn't go amiss, along with the usual
regression testing.
