freebsd-update: following files will be updated ... /usr/share/man/whatis

[tonycheed at vfemail.net]

Hello

Some time ago I have added this:

@daily	root	freebsd-update cron

to my '/etc/crontab'. (Just in case I miss security, errata etc. 
notification e-mails, I still get the nightly e-mail directly from the 
host...)

Ever since then I get a mail every night telling me a new version of 
'whatis' is available (actually, almost every night -- after real 
updates there is silence for a few days):

doing here, why and what to do about it?
