I committed the attached.

Regarding the release notes, I take it that we should modify
doc/src/sgml/release.sgml? Does the following sound reasonable, or
should I provide specific examples?

<listitem>

considerably. Junk that was previously allowed in odd places with
odd results now causes an ERROR. Also changed behavior with respect
to whitespace; trailing whitespace is now ignored as well as leading
whitespace (which has always been ignored).
