The original titles only had the module name, which is not very useful
when scanning the list. By adding a very brief description to each
title, the table of contents becomes friendlier.
Also amend the introduction in the "additional modules" appendix, using
the word "Extension" more extensively. Nowadays, almost all contrib
modules are extensions, so this is also helpful.

For DocBook XML compatibility, don't use SGML empty tags (</>) anymore,
replace by the full tag name. Add a warning option to catch future
occurrences.
Alexander Lakhin, Jürgen Purtz
Block elements with verbatim formatting (literallayout, programlisting,
screen, synopsis) should be aligned at column 0 independent of the surrounding
SGML, because whitespace is significant, and indenting them creates erratic
whitespace in the output. The CSS stylesheets already take care of indenting
the output.
Assorted markup improvements to go along with it.
