They were probably added at different times; I don't think there's any
reason why they can't be combined into one function.

That's an artifact from maxima.el, where waiting for the output was
causing problems.  There were some cases when the output was being
yanked into a different buffer but the output was truncated, and this
was a tweak to wait a bit longer for output if necessary
(`axiom-after-output-wait' was customizable and could be increased).

In that case, `(setq comint-prompt-regexp axiom-prompt)' shouldn't be
necessary.

I'm surprised.
When I changed the value of `axiom-args' from "-noclef" to "", axiom
mode no longer accumulated all output and displayed it at once, and
when I started Axiom in an xterm with "axiom -noclef", it then did
accumulate all output and displayed it at once.  I don't have
wh-sandbox, though.

What works?  Axiom mode will display the output incrementally, rather
than all at once?

What code is being run while Axiom output it arriving?
