The issue is this is the only wpot where matching is done this way.

On the data section the comparison is not present. All it does is clean
out the ttrailing spaces

	$_->{service_name} =~ s/\s+$//g;

I guess the other match is because the service result contained a match on
the service_name definition.

Fixing this lot to make sure it is more fool proof may take a while.
Perhaps if I have to babysit an upgrade without much else to do and I have
the whole script in paper in front of me.  (Which may be months from now.)

Hugo.
