This seems to conflict, in scope, with 1.1 -- I'll pose a couple other
examples where I'm not sure about 1.1 once I get there.

No problem here, but contrast it with point 2.2.

So a set of GIMP bump maps is not software?  How about wave tables which
represent midi instruments for some sound card?

[bump maps can be any graphical image loadable by the gimp.  wave tables
can be sound samples.  The point being that the difference between code
and data depends on your point of view, and that as technology is developed
we're going to find our point of view drifting.]

If we're going to have some kinds of files which can be redistributed
without meeting these guidelines, I'd prefer to have them explicitly
described -- and then we still need guidelines for what kind of license
we expect on those files.

This gets confusing if you consider modification and distribution as
forms of use.

Is this a recursive reference to this document?

[I think the point is that the source code for a DFSG-free executable
must also be DFSG-free.  However, there's no definition for source code,
so cases like the original source is compiled into unreadable C are
going to be ambiguous.]

This seems to imply that the emacs license can't prohibit someone
from removing its copyright display at load time.  [Because that's
where the >>unmodified<< software displays copyrights.]

You might want to define "compatible".  [Remember how the old Qt license
said it was compatible with the GPL, even though the converse wasn't
