I agree, good job!

Btw, the Windows instructions are somewhat inaccurate.  They say:

  Unzip the zip file and run bin\emacs.exe.

A better text would be:

  Unzip the zip file preserving the directory structure, and run
  bin\runemacs.exe.  Alternatively, create a desktop shortcut to
  bin\runemacs.exe, and start Emacs by double-clicking on that
  shortcut's icon.

Thanks.
