Merge from knu-cvsweb 1.110.1.78.

• cvsweb.cgi, cvsweb.conf: Support "zip" as an additional

archiver.

• cvsweb.cgi: MFZ 1.110. But the bug had already been fixed in

knu-cvsweb.

2001-06-22 Akinori MUSHA <knu@iDaemons.org>

• cvsweb.cgi: Get rid of a potential "uninitialized variable

usage" warning.
