/**
* Roughly speaking, get the next message-id (starts with a '<' ends with a
* '>'). Except, we also try to handle the case where your reference is of
* a prehistoric vintage that just stuck any old random junk in there. Our
* old logic would (unintentionally?) just trim the whitespace off the front
* and hand you everything after that. We change things at all because that
* same behaviour does not make sense if we have already seen a proper message
* id. We keep the old behaviour at all because it would seem to have
* benefits. (See jwz's non-zero stats: http://www.jwz.org/doc/threading.html)
* So, to re-state, if there is a valid message-id in there at all, we only
* return valid message-id's (sans bracketing '<' and '>'). If there isn't,
* our result (via "references") is a left-trimmed copy of the string. If
* there is nothing in there, our result is an empty string.) We do require
* that you pass allowNonDelimitedReferences what it demands, though.
* For example: "<valid@stuff> this stuff is invalid" would net you
* "valid@stuff" and "this stuff is invalid" as results. We now only would
* provide "valid-stuff" and an empty string (which you should ignore) as
* results. However "this stuff is invalid" would return itself, allowing
* anything relying on that behaviour to keep working.
*
* Note: We accept anything inside the '<' and '>'; technically, we should want
* at least a '@' in there (per rfc 2822). But since we're going out of our
* way to support weird things...
*
* @param startNextRef The position to start at; this should either be the start
* of your references string or our return value from a previous call.
* @param reference You pass a nsCString by reference, we put the reference we
* find in it, if we find one. It may be empty! Beware!
* @param allowNonDelimitedReferences Should we support the
* pre-reasonable-standards form of In-Reply-To where it could be any
* arbitrary string and our behaviour was just to take off leading
* whitespace. It only makes sense to pass true for your first call to this
* function, as if you are around to make a second call, it means we found
* a properly formatted message-id and so we should only look for more
* properly formatted message-ids.
* @returns The next starting position of this routine, which may be pointing at
* a nul '\0' character to indicate termination.
