Thanks - I now have a (superficial) understanding of what's going on, after browsing
the source, particularly where Magnus indicated.

Only one remaining mystery remains (no need to worry about this; I'm just recording
yet another puzzle):

The Sanitizer.php file has exactly one occurrence of 'q', and that occurrence is
commented out. Versions more than a year old have the same.

Yet tests show that:
   wikitext <x whatever> is &lt;x whatever&gt; in the html source
   wikitext <q whatever> is <q> in the html source ('whatever' omitted)

We expect the <x whatever> behaviour because 'x' is not recognised as an html
element. However, I can't find anything in Sanitizer.php which recognises 'q'.
