r338:    * Patch from Jorgen `forcer' Schaefer <forcer at mindless.com> (much
     modified)to make dh_installwm use new window manager registration method,
     update-alternatives. Closes: #52156, #34684 (latter bug is obsolete)
   * Fixed $dh{flavor} to be upper-case.
   * Deprecated dh_installemavcsen --number; use --priority instead. Also,
     the option parser requires the parameter be a number now. And,
     dh_installwm now accepts --priority, and window manager packages should
     start using it.
   * dh_installwm now behaves like a proper debhelper command, and reads
     debian/<package>.wm too. This is a small behavior change; filenames
     specified on the command line no longer apply to all packages it acts
     on. I can't belive this program existed for 2 years with such a glaring
     problem; I guess most people don't need ot register 5 wm's in 3
     sub-packages. Anyway, it can handle such things now. :-)
   * Moved Dh_*.pm to /usr/lib/perl5/Debian/Debhelper. *big* change.
