https://en.wikipedia.org/wiki/Arial has,
"It [Arial] was created to be metrically identical to the popular typeface 
Helvetica, ... so that a document designed in Helvetica could be displayed 
and printed correctly without having to pay for a Helvetica license."

With no font-family in the <span style= ...> tag, the wikibook delivers 
HTML which the browsers here render in fixed pitch.  To avoid that 
I specified fontFamily = "Arial" in the MediaWiki module.  Maybe 
"Helvetica" would work better after all.  Advice?

> Changing a tab character into a fixed number of blanks is done easily ...

Good.

Considering that Joerg contibuted V4Sort, additional adjustments are 
according to his conventions.  
https://en.wikibooks.org/wiki/User:PeterEasthope/sandbox 
Probably some errors remain and I'm happy to edit further before 
moving from the sandbox to a book page.  

A "Stylistic Conventions" section can be added to the book later.

I've never used any of the contexts or softwares listed in the subject 
line. In the future my efforts will probably focus more on the EO and 
Oberon contexts.  The book is a wiki and anyone is welcome to pitch 
in.
