Thanks for the hint.  The following line seems to do what I want:

  AppendIfNoLineMatching "cfengine[[:blank:]]+5308/tcp.*"

Ough!  This is a pretty non-standard behavior.  Why is this needed?  As
long as no '$' is used at the end, the '.*' should not make any difference.
I don't know any regex implementation that makes such a requirement.
If this behavior is by intention, then it clearly needs to be properly
documented, since this is a big deviation from the standard (which is to
automatically ignore leading/trailing contents unless '^' or '$' is used).

BTW: The documentation don't say that the sqare brackets need to be
     doubled as shown above.  Maybe the documentation should be
     extended accordingly?
