They're just extraneous here.  They don't cause any problems, either.  You
could use quotes around everything if you wanted, and it would still do the
same thing:

    "/appl/fp/rclerk" "msx.served" "-s1" "-z" "addfile"

The only time you _need_ quotes is when the thing within the quotes has
something that the shell would act on, such as whitespace in a -H header
text, or wildcards (perhaps also in -H text).

For example:

    /appl/fp/rclerk filename -h "This is a header"
