The problem I have in mind is the following: I am considering using
MathML for the output of a symbolic algebra program, Maxima. What I'm
worried about is displaying machine-generated code that will not fit on
a single line. If Maxima is to provide the line breaks, how can it
possibly decide how to do it? If Maxima is going to expect the MathML
display software to do the breaking, is that a reasonable assumption?
I.e., do any available MathML display tools do that?

Perhaps it's just that I'm unfamiliar with the lingo, but I don't know
exactly what you mean by "overscanned."
