[Bug 985149] [NEW] Add List-Post value to permalink hash input

[Richard Wackerbarth]

Barry,

I definitely agree that "Now's the time".

I don't understand the proposal. By "added to this hash", do you mean
"included in the set of elements that get hashed" or do you mean
"appended to the hash value"?

Presumedly, the sole purpose in publishing an algorithm to create the
hash is to make it possible for two handlers to independently develop
the same hash given only the message. Otherwise, a "secret" method could
be used to assign a unique identifier to the message.

In either case, this suggested change renews my argument that the
resulting hash should be tagged, visibly, with a "protocol revision
designator". Omitting that designation transforms the chosen calculation
method into a "secret".
