[PATCH] docs pages containing <source> are sometimes too wide

           Summary: [PATCH] docs pages containing <source> are sometimes too

The document2html.xsl stylesheet renders <source> elements as HTML <pre> 
elements, which can make the resulting pages too wide to see on screen or 
print. This stylesheet appears not to have changed for ages.The "modules" page 
in the URL field shows the problem. This page is too wide for display on most 
screens. A web page that is wider than the screen is a complete bastard to 
read - you have to scroll left and right all the time. And printing in 
landscape orientation is not very nice either. 

The problem is:

1) Browsers usually render <pre> elements in a fixed-width font, which are 
always wider than normal fonts.

2) There is no line-wrapping in a <pre> element, so a single long line of 
source can make the web page very wide.

The patched stylesheet includes an extra template to render simple <source> 
elements (i.e. those which contain only text content) as a <div> containing a 
sequence of <p> elements. The font itself is not specified, so it will 
generally be a proportional font. The font size is reduced anyway ("smaller"). 
The template uses CSS "style" attributes to retain the original indentation 
while allowing line-wrapping. A single space of indentation is rendered as a 
4pt indent. Where a line of source wraps, the subsequent line is further 
indented by 8pt (i.e. equivalent to 2 spaces).

This new XSL code treats the content of the <source> element as a single 
string, so I have left the old template in place to handle <source> elements 
that contain extra markup.
