For those who prefer Github's UI, I've posted Dick's diff to a branch
commit in our repository [1].

The diff contains a number of editorial suggestions, such as removing use
of ABNF, which we can consider separately.  The key substantive change, as
discussed earlier in this thread, is to make comma-escape handling for
value lists happen during character-string escape parsing, instead of
afterward.

In the implementations I've worked on so far, this change would be highly
inconvenient to implement, as it conditionally modifies the core
character-string parsing loop that has thus far been entirely
RR-type-independent and shared by all zone-file parsing contexts.

The only way I can see to accommodate both of these implementation
perspectives is to allow implementors to avoid the offending special case,
which, as I've noted before, is not currently needed, and may never be
needed.  I have proposed a change [2] that would add this option (now
updated to avoid conditioning requirements on the IANA registry, in
response to feedback from Paul Wouters).
