Major changes between sudo 1.8.19p2 and 1.8.19p1:
* Fixed a crash in visudo introduced in sudo 1.8.9 when an IP address
or network is used in a host-based Defaults entry. Bug #766
* Added a missing check for the ignore_iolog_errors flag when
the sudoers plugin generates the I/O log file path name.
* Fixed a typo in sudo's vsyslog() replacement that resulted in
garbage being logged to syslog.
