Rn, trn, and strn "^G" functionality skips to the next occurance of
"Subject:" in column one.

GNUs has two "digest" parsers.  One insists on full RFC1153 compliance
(main Subject: line "digest" tokens etc.), and the other skips to lines
with (at least 8?) hyphens starting in column 1.

Tin has no digest functionality at present, though, tin's author indicates
willingness to add it in a way compatible with this format.  This author
suggests either the "^Subject:" or "^-*" approach.

Nn triggers on Subject: plus From: which is often not applicable
to FAQs.  Nn "explodes" FAQs with both Subject: and From: subheaders
into individual articles.  Most nn users this author has discussed this
with do not want FAQs to behave this way, which is why this format doesn't
require "From:" lines.

Thomas Fine's FAQ to HTML conversion system uses a scoring system to
measure compliance with the:

	<blank line>
	<line of hyphens>
	<blank line>
	Subject: <subject>

format.  See the following for more detail:

I would appreciate detail on digest/FAQ parsing in other newsreaders and
conversion systems.
