Bug: "--hostformat split" and hostnames with dashes

==== Debian package: logwatch
==== Version: 7.4.0+svn20120502rev103-1

==== Problem: 

Hostnames with dashes in them cause "--hostformat split" to report on
log messages for the wrong host. For example, the report for moose gets both
of these messages instead of just the first.

Oct 30 13:06:06 moose-web sshd[8049]: Accepted publickey for frank from 95.111.111.11 port 22 ssh2

==== Fix: 

The pattern that the onlyhost script uses to match against hostname uses \b:
if ($line =~ m/^... .. ..:..:.. $hostname\b/io) { 

Instead it should use \s:
if ($line =~ m/^... .. ..:..:.. $hostname\s/io) {
