Hmm.  We may not want to get down to that, still that would be
cheaper than reprocessing the parsing of the query string twice.

Okay.  I could fall into that for this release.  Marking the
JumbleState as a const is the most important piece here.  I'm +-0
regarding this routine, but I can also see your point about how it's
useful to give at least the option to extensions to have a
recomputation of the Const lengths, the same way as PGSS.  What are
the extensions that would use that?
