Producing those patches would be a lot of work even to incorporate, let 
alone write.  Another possibility is some sort of markup in the display 
to indicate platform-specific bits.  That would be a lot easier to 
implement; the hard part is the design. 

We have to design for 4 different output formats:  LaTeX, HTML, plain 
text, and executable example code.  We need to design for help files 
that display differently on different platforms, and for help files that 
only exist on a subset of the platforms.
