backslashes anymore. A single backslash is enough. Changed the
definition in all affected packages. For those that are not caught, an
additional check is placed into bsd.pkginstall.mk.
And always is defined as share/examples/rc.d
which was the default before.
This rc.d scripts are not automatically added to PLISTs now also.
So add to each corresponding PLIST as required.
This was discussed on tech-pkg in late January and late April.
Not all of these packages have been tested.
Todo: remove the RCD_SCRIPTS_EXAMPLEDIR uses in MESSAGES and elsewhere
and remove the RCD_SCRIPTS_EXAMPLEDIR itself.
