RE: Three-Line service comments

I understand, but many sysadmins are used to using this comment style
and there are a number of software packages that automatically install
themselves in this way, so if I can use cfengine to maintain the file
as-is then I can concentrate on configuring cfengine for our site,
rather than the other way round.  We have a lot more systems than I have
cf files.  :-)

Another multi-line problem I've encountered is systems that use the '\'
character for continuation lines, eg HP-UX 11 systems often contain a
line in inetd.conf like:

tftp        dgram  udp wait   root /usr/lbin/tftpd    tftpd\
        /opt/ignite\
        /var/opt/ignite

Cfengine won't be able to comment out this entry safely.  I couldn't see
any way of joining up the continuation lines within cfengine, so I've
added another perl segment to fix these up before normal processing
(unless they're already commented out), eg:

      SetScript "perl -00 -pi -e 'BEGIN{pop};s/\s*\\\n\s+/\t/g'"
      RunScriptIfLineMatching "^[^#].*\\$"
