They are not likely to go any time soon, because they require
non-standard tools to make. Obviously it's something I have my eye on,
though. I am a bit annoyed that we have _two_ identical copies (in
etc/charsets and admin/charsets/mapfiles) of some of these generated
files in the repo! ;)

BTW, this .bzrignore pattern:

*.map

is far too broad. Eg

  bzr status etc/charsets/MULE-ipa.map
  -> ignored:
     etc/charsets/MULE-ipa.map

It seems to be some Windows thing; can it be restricted?
