We need line-breaking for MathML

[holtzermann17]

For example, here:
http://planetmath.org/quarticformula

Is there a line wrap mode to turn on in either LaTeX or LaTeXML or both? ... what to do here?

For LaTeXML, I suggest using the "linelength" parameter which implements a MathML breaking algorithm for presentation MathML. The "right way" of doing that would be to use the right CSS3 property for line-breaking MathML, but pretty much no browsers currently support that adequately.

Which is exactly why LaTeXML has that implemented separately. I can add the parameter to the planetmath conversion profile, if you wish?
