I'll reluctantly concede that point.  (But see below.)

Not relevant; the program in question wasn't using it in an identifier.  That
was, in fact, the point: the Standard requires that any implementation in
which `$' is in the source character set (in practice, any implementation in
the ASCII-or-superset world) *must* accept the program and generate a result
contrary to what is produced by the traditional DEC or Apollo compilers.

I figure it's a Quality of Implementation issue.  An implementation that
disallows "`" in a comment probably won't survive long in a free market.
(And if some of the characters in my source file cause a change in shift
state when interpreted in the implementation's character set, then the vendor
had better supply a translator that maps my character set into his.)
