I don't know what your problem is with texi2any's use of MathJax.
Why are MATHJAX_SCRIPT and MATHJAX_SOURCE not enough?

I don't know why you say there are no line breaks.  For example:

@displaymath
 f(x)
= {1\over\sigma\sqrt{2\pi}}
     e^{-{1\over2}\left({x-\mu\over\sigma}\right)^2}
@end displaymath

This becomes in HTML (with -c HTML_MATH=mathjax):

<div class="displaymath"><em class="tex2jax_process">\[ f(x)
= {1\over\sigma\sqrt{2\pi}}
     e^{-{1\over2}\left({x-\mu\over\sigma}\right)^2}
\]</em></div>

I tested this in "lynx" and it looks as follows:

   \[ f(x) = {1\over\sigma\sqrt{2\pi}}
   e^{-{1\over2}\left({x-\mu\over\sigma}\right)^2} \]

The content is breaking, just not at exactly the line breaks in the
HTML source.

In TeX, a single line break is equivalent to a space, so there is
no loss of meaning.
