What I have locally is the Emacs 20 manual, which is not under GDFL
but says (when I look at emacs.info with less)
| Permission is granted to copy and distribute modified versions of
| this manual under the conditions for verbatim copying, provided also
| that the sections entitled "The GNU Manifesto", "Distribution" and "GNU
| General Public License" are included exactly as in the original, and
| provided that the entire resulting derived work is distributed under the
| terms of a permission notice identical to this one.
I have been assuming for the discussion that the GNU Manifesto is
still invariant in later versions of the manual. For those who like
to count bytes, the manifesto takes up some 25 KB of text in info
format.

I imagine the problem of borrowing a few pages of technical
documentation for another project, but then being stuck with 25 KB of
political proselytizing.

According to the license text above, it does (and also according to
what I can remember from the GFDL).

The problems I am worried about are not so much about having
unmodifiable text as such (as long as it is not technically
important), it's having the unmodifiable text tied to technically
relevant text (such as technical documentation).
