If the question is whether I am now satisfied that none of the issues
raised in this thread present any implementability issues, then no: I
continue to believe that the text does not give enough information for
implementors to know the intended behaviour.  (I've since learned that
I'm not the first implementor to post to www-style expressing
uncertainty as to the behaviour intended by the text.)

As for whether there's anything particularly valuable and easy to
consider changing:

  Clarifying what "while parsing a declaration" means would be one
  candidate: the tests I tried had uniform results in all UAs I tested,
  and would go a long way towards answering one of the queries I had to
  do with handling errors "while parsing a statement".  Some suggested
  text appears in the while-in-decl.html file
  (http://bowman.infotech.monash.edu.au/~pmoulder/html-tests/while-in-decl.html).

  Another candidate (by virtue of being cheap to edit) would be to copy
  & adapt the last paragraph of the "unknown at-keywords" rules to
  append to the "malformed statements" rule.
