r1905: * dh_installxfonts: pass --x11r7-layout to update-fonts-* commands to ensure
  they use the right new directory. Closes: #362820
* dh_installxfonts: also, alias files have moved from /etc/X11/fonts/* to
  /etc/X11/fonts/X11R7/*, update call to update-fonts-alias and the man page
  accordingly; packages containing alias files will need to switch to the
  new directory on their own.
* dh_installudev: correct documentation for --name. Closes: #363028
* Fix broken directory removal code.
