Oh!  I hadn't fully absorbed the following, but it seems then that rms
believes that the restriction like that on the Emacs manual (that you
must redistribute certain extraneous pieces) does not violate freedom
3 of the FSF's Free Software Definition:

    * The freedom to improve the program, and release your
      improvements to the public, so that the whole community benefits
      (freedom 3). Access to the source code is a precondition for this.

(whether or not the work in question is documentation), while I
believe the Debian people decided early in the discussion that a
similar restriction on software would violate point 3 of the DFSG:

  3. Derived Works

     The license must allow modifications and derived works, and must
     allow them to be distributed under the same terms as the license
     of the original software.

Actually, I'm a little unclear on the latter point.  To what extent
are non-functional restrictions OK for Debian?  For instance, the
GPL's clause 2c (message at an interactive prompt) is uncontroversial,
but the much longer message that the reiserfs utilities printed seemed
to be more questionable (if it were required by the license, and aside
from the fact that it was incompatible with the GPL).  Or is the
question whether the restrictions in the GFDL are truly

(I note that FSF's freedom 3 is more focussed on improving the
program, i.e., functionality, while DFSG 3 is stated more broadly.)
