After some investigating, I found that several people who made commits
are not mentioned at all (neither in THANKS, nor in AUTHORS)!

People I added to AUTHORS:

- Arne Babenhauserheide: he added 'mercurial' package.

- Ian Denhardt: he added 'feh' package, 'version-prefix' and
  'version-major+minor' procedures, and some other things.

- Kevin Lemonnier: he added 'zsh' and 'weechat' packages and a patch for
  'lua'.

- Mathieu Lirzin: he added 'markdown', 'xbindkeys' and 'dionysus'
  packages, and moved HACKING to the manual!

- Pierre-Antoine Rault: he added 'python-dbus' package.

- Ben Woodcroft: he added several bioinformatics packages.


People I added to THANKS (or should they be moved to AUTHORS?):

- Konrad Hinsen: he added some documentation.

- Cyprien Nicolas: he added 'guild' check to "configure.ac" and fixed a
  couple of typos.

- Yakkala Yagnesh Raghava: he fixed a typo in Nixpkgs URL.

- Alexander Shendi: he added 'libx11' input to 'mit-scheme' package.


I hope I didn't miss anyone.  The modified patch is attached.
