Changes:
2.12.12:
- Recognize references in ABNF comments. Since v2.08.03 references in ABNF
parts of a document have been ignored, to avoid spurious warnings because of
bracketed ABNF explressions; but within ABNF comments it is appropriate to
register references.
2.12.11:
- Added support for explicitly noting downrefs for which excemptions has been
granted in the past (based on
http://trac.tools.ietf.org/group/iesg/trac/wiki/DownrefRegistry).
2.12.10:
- Added diagnostic messages for various downloaded status files when running
in verbose mode.
