Many documents (in the U.S., any document published before 1923, YMMV)
are in the public domain.

Not so, unless the referent of "it" is shifting.  The resultant 
modified document can be copyright as to the modifications, but not
the original.  Once in the public domain, always in the public domain.

Impossible.  They could at best be prevented from using the modified
form.  This is important for software where the PD version may be
unmaintained and so people have to go to the commercial version if
they want the latest fixes, but less so for more static kinds of
content.

I think that the copyright laws are not the proper way to maintain this
principle.  After all, doubting users can always download the
authentic version from the author's website.  If you are truly
concerned, however, a rewritten version of the Artistic License
(http://www.opensource.org/artistic-license.html) may help you.

Unfortunately, authors (as distinct from sculptors, painters, etc.)
have no moral rights that international law recognizes as worthy of
protection.  I always insist on "the moral right to be known as the
author of this document", but this has no legal force, unlike the
analogous claim by a visual artist.
