(:nl:) adds a newline only if there isn't one already there.
Thus,  

    (:include Group.SomePage)(:nl:)This is some text

will add a newline only if Group.SomePage doesn't end with a newline.
This is so that we can be sure that "This is some text" appears
at the beginning of a line, without adding an extra (blank) line
when it's not needed.
