r294:    * Fixed problem with dh_installemacsen options not working, patch from
     Rafael Laboissiere <rafael@icp.inpg.fr>, Closes: #47738
   * Added new dh_installxfonts script by Changwoo Ryu
     <cwryu@dor17988.kaist.ac.kr>. Closes: #46684
     I made some changes, though:
     - I rewrote lots of this script to be more my style of perl.
     - I removed all the verbisity from the postinst script fragment, since
       that is a clear violation of policy.
     - I made the postinst fail if the mkfontdir, etc commands fail, because
       this really makes more sense. Consider idempotency.
     - I moved the test to see if the font dir is really a directory into the
       dh_ script and out of the snippet. If the maintainer plays tricks on
       us, mkfontdir will blow up satisfactorally anyway.
     - So, the snippet is 9 lines long now, down from 20-some.
     - I realize this isn't following the reccommendations made in Brandon's
       font policy. I'll fight it out with him. :-)
     - In postrm fragment, used rmdir -p to remove as many parent directories
       as I can.
