keithmarshall pushed a commit to branch master
in repository groff.

commit 94d17a8ca577da9dda9296deb700248e23be63cb
Author: Keith Marshall <address@hidden>
Date:   Sun Oct 12 22:17:44 2014 +0100

    [pdfmark] Avoid spurious user visible control messages on stderr.
    
    * pdfroff.sh (REFCOPY): Ensure that at least one pdfhref mark of type
    'Z' will remain in the reference map, after all references have been
    resolved; this is required, to suppress writing of reference control
    records to stderr during the final PDF output processing phase.
