The construct:
<citerefentry>
<refentrytitle>foobar</refentrytitle>
<manvolnum>1</manvolnum>
</citerefentry>
is a pain to type, and messes up the pretty-printing of the source code.
Replace every occurence of a entry like that with:
&man.foobar.1;
Adjusting the manual page name and section number appropriately.
The definitions for these entities are stored in man-refs.ent. This
file is in doc/share/sgml because it is not just specific to the Handbook.
I expect the DocBook'd FAQ and Tutorials (coming RSN) to use them as
well.
A new PUBLIC identifier has been created for these entities, and added to
the catalog file.
Doc. Proj. related ports under $PREFIX/share. Update en/handbook/Makefile
with the new paths.
Didn't seem worthwhile to do a repository copy for only three files moved.
