Actually, I wonder whether the current application of the GFDL for
GNU manuals is internally consistent at all.
For example, the GNU diffutils manual is licenced with the Front-Cover
Text "A GNU Manual". Say now that I'm a FooBSD user who for some
reason have become dissatisfied with the quality of the documentation
for diff that FooBSD ships with (this is a hypothetical example; I
have access to no *BSD systems and don't know anything about the
actual state of their documentation). So I take the texinfo source for
the GNU diffutils manual and hack upon it so that it describes FooBSD
diff.
Now I have a manual for FooBSD diff whose license says that it needs
to be called "A GNU Manual" on its front cover. That could be somewhat
confusing for users - does this document describe the FooBSD or the
GNU implementation of diff? And is this front-cover text even
compatible with the requirement that I remove all Endorsements?
Worse yet, my FooBSD diff manual must say on its *back* cover: "Copies
published by the Free Software Foundation raise funds for GNU
development" which is rather meaningless as long as the FSF does not
publish copies of the FooBSD version of the manual at all!
