Hi Neal--

Thanks for the nit-picks.  Two concerns:

what does the [ ] you've inserted here mean?  It looks like a markdown
todo-list "checkbox", maybe it was inserted by mistake?

This seems like a mistake.  C0 and C1 could be specific hexadecimal
octets (decimal 12), whereas "c0" and "c1" here are intended to be
placeholders for the checksum.  This is a bit confusing, maybe it would
be better to use s0 and s1 (s for "sum") so that it's clear that it
isn't hex?

At any rate, i think this was the only "capital hex" part of the diff,
so we probably don't need that mention in the commit message either,
right?

I've included this proposal (without the two changes above that i think
are mistaken) and your other remark about the big-endianness of the
two-octet scalar in a merge request:

   https://gitlab.com/openpgp-wg/rfc4880bis/-/merge_requests/38

I encourage people to make merge requests directly in gitlab in addition
to posting patches to the mailing list, especially for
non-substantive/editorial changes like this.
