        pdfroff.sh portability enhancement.

        * pdfroff.sh: (ARGLIST): Variable removed.
        (GROFF_STYLE): Use it for all groff invocations.
        (INPUT_FILES): Pass to all groff invocations, instead of ARGLIST.
        (CS_MACRO, CE_MACRO): Initialise independently.
        (CS_FILTER): Simplify quoting; it used to confuse some shells.
        (Source): CVS keyword removed; replaced by...
        (RCSfile, Revision): these.
