Make "check_diff new_only" not generate spurious emails

Many periodic scripts check log files and generate an email if there is something new.

Often, you receive spurious emails like this:

> myhost kernel log messages:
>  
> -- End of security output --

Obviously, there are no log messages to report.

Reason is a logic error in "check_diff new_only" which should generates a message only if there are new lines in given log. Unfortunately, a message is also generated if there are __removed__ lines, even though those removed lines are not shown (and not meant to be shown).

I've attached a fix.

I still get spurious get emails from periodic security scripts.

Could you/someone please apply the patch?
