Many of these are, unfortunately, nearly-valid ABNF.

It thinks this text is a continuation of the previous rule, since it's indented.

Similarly, this text appears to be a continuation.

aex's tradeoff is to over-extract; I have to edit its output about 40%
of the time but it always (as far as I've been able to tell) gets all
the ABNF in a document.  I'll see if I can straightforwardly teach aex
what characters can appear unquoted in ABNF, that will help some of
the false positives (I think all the examples you gave have commas in
the false positives, for example)
