Cfengine 2.1.8 purge=true verbose bug

[Stephen Haynes]

With the recent moving of the code to warn about purging of NFS mounted
file systems it has uncovered a related bug in Cfengine 2.1.8.

I now recieve the following message when running cfagent in verbose mode
for a copy that has purge=true set when I have a server defined.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!! Purge detected in local (non-cfservd) file copy to file /var/cfengine/inputs
!! Do not risk purge if source /srv/cfengine/inputs is NFS mounted (see manual)
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The patch is as follows:
