Re: draft for new Vim license

[Richard Stallman <rms@gnu.org>]

	   c) Provide the changes, including source code, with every copy of the
	      modified Vim you distribute.  This may be done in the form of a
	      context diff.  You can chose what license to use for new code you
	      add, so long as it does not restrict others from changing the
	      official version of Vim.

    This prevents someboy from adding a patented item and not permitting
    others to add a similar item to Vim.

I am not convinced those words really do this job.  The difficulty is
that, in such a case, it is not "the license for the new code" which
restricts others, but rather the patent which does so.

Maybe these words would do the job:

	   c) Provide the changes, including source code, with every
	      copy of the modified Vim you distribute.  This may be
	      done in the form of a context diff.  You can chose what
	      license to use for new code you add, so long as it
	      permits others to include all or any part of this new
	      code in a subsequent official version of Vim.

And you might want to add

"... and release it under this License."
