It has been the cause of much grief to us. Annoying beyond belief!!!!!!!!!!

We are using Mathematica to capture design rules for modular systems, to a large
extent because of the readability of the rules. The ability to mathematically
typeset equations, mix text and outlining with functions, highlight sections in
boxes and colors, etc., has proven very useful.

But all of our rule bases eventually get run as *.m files. We use Mathlink for
Excel, which requires the *.m files. And then the pain starts. Tracking down all
of the spurious and unjustified formatting errors is enormously painful. You end
up just wanting to strip out all of the formatting you initially had  in order
to get the *.m file to work, almost completely defeating the original reason for
using Mathematica.

I've been contemplating a macro that would operate on a *.m file and remove all
formatting that got carried over in the conversion of a notebook to a .m file.
Call it a "Plainifier".

A true statement, and maddening to the user!

Thanks for the suggestion...
