   * debian/rolltarball.sh:
     Cherry-picked from Arctica GH 3.6.x branch.
 .
     - Use more quotes. Fixes potential bugs, including one triggered by an
       unquoted hash within the command line. BASH accepts this. Other shells
       do not (i.e., treat everything following the hash character as a
       comment.)
     - Convert tabs to spaces for consistency.
     - Use more curly braces. Prevents random characters as being treated as
       part of a variable name.
     - Don't escape last newline of a multiline command. Worked out fine so
       far, because the next line was empty, but this can easily change...

   [ Michael DePaulo ]
   * {nx-X11,nxproxy}: correct manpages: --help -> -help
     xorg-server does not follow the convention of using 2 dashes.
     Note that --help does produce the help output. However, it
     produces this additional output after it:
     Error: Aborting session with 'Unrecognized option: --help'.
     Session: Aborting session at 'Sun Jun 28 01:35:35 2015'.
     Session: Session aborted at 'Sun Jun 28 01:35:35 2015'.
     It also causes a return code of 1 rather than 0.
     Therefore, we should instruct users to call -help instead.
