I spoke too soon.

While we need to consider multiple spaces, we did decide quite some time
ago that a header always had a space after the colon. So the tab case can
be ignored.

becomes, more simply:

    The line consists of the article number, a space, and then the
    contents of the header or metadata item.  In the case of a header,
    the header name, colon, and the first space after the colon are
    all omitted.
