For typical software like Emacs, release tarballs tended to include the
results of running autoconf and makeinfo, excluding version control
system specific files (things like .gitignore) and the instruction files
for getting from vcs checkout to release tarball state.  The usual
situation was that you needed no part of the Texinfo chain or of the
autoconf tools (including m4) to build from unmodified source.

So there was considerable and non-trivial difference between a vcs diff
and a release tarball diff.  And the instructions reflect that.

I am not really all too sure how to apply this to our situation.  At
present, I think most people would not really be interested in a
separately downloadable diff anyway.
