htdig bug fix update

Updated htdig packages that resolve several issues are now available.

The ht://Dig system is a complete World Wide Web indexing and searching
system for a small domain or intranet. This system is not meant to replace
the need for powerful Internet-wide search systems like Lycos, Infoseek,
Webcrawler and AltaVista. Instead, it is intended to cover the search needs
for a single company, campus, or even a particular subsection of a website.
As opposed to some WAIS-based or web server-based search engines, ht://Dig
can span several web servers at a site, as long as they understand the HTTP
1.0 protocol.

These updated htdig packages provide fixes for the following bugs:

* updating the htdig packages incorrectly removed configuration files,
which were written over with the original configuration files. This no
longer occurs with these updated packages.

* in cases where htdig attempted to run the parser configured in the
"external_parsers" attribute in the htdig.conf configuration file, and
running that parser failed, then htdig could attempt to parse its own error
messages. With this update, htdig is prevented from parsing data
incorrectly in such a manner, exits from such a situation correctly, and
displays an improved error message when running the external parser fails.

* running "htfuzzy soundex" after indexing with htdig resulted in spurious
error messages when the "allow_numbers" attribute of the htdig.conf
configuration file was set to set to true.

* calling either the "htstat" or "htfuzzy" command when the database
contained zero words resulted in a segmentation fault, which has been fixed
in these updated packages.

All users of htdig are advised to upgrade to these updated packages, which
resolve these issues.

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
