Comment #17 on issue 87 by quinntay... at mac.com: ch06: mention 'htdigest'  
tool when mentioning digest auth

I revised my changes related to svn.serverconfig.httpd.authn (including  
both Basic and Digest authentication) and included a few additional related  
changes in other sections to improve consistency and readability. Attached  
is a diff against rev 3897.

There were a few spots which switched to <example> / <programlisting>, but  
they were inconsistent with the rest of the file, which uses  
<informalexample> / <screen> for httpd.conf and svnserve.conf configuration.
