Comment(by nbruin):
the lisp function {{{retrieve}}} in maxima is responsible for asking
questions, so we just monkey-patch it to throw an error with an
informative message instead. The patch trac_7377-better-ask-error.patch
improves the readability of this message by executing exactly the original
code in retrieve, but wrapped in a {{{(with-output-to-string (*standard-
output*) ...)}}}. The method is generally applicable and may be useful in
adapting other printing bits.
Oddly enough, this patch does not invalidate any additional doctests, but:
{{{
sage -t "devel/sage-devel/sage/interfaces/maxima_lib.py"
**********************************************************************
Error: TAB character found.
}}}
so perhaps maxima inserts a TAB in the error message. Are TABs not allowed
in doctest output?
(it looks like one gets produced and matched by a "..." in the doctest
template). A {{{sage -t --verbose}}} shows that no individual test fails.
