yes and I think the sa was just for some cases like with brivla or
cmevla,  and some nesting cases. Otherwise yes I think his peg
supported the magic words pretty well. I also thought he had some
nonstandard extensions as well though?

I agree. And think the rule I just stated is an optimazation and still
accomplishes what I think the intent was. I don't know enough to
really say though.

http://pdf23ds.net/lojban/Annotated%20Grammar.html and
http://digitalkingdom.org/~rlpowell/hobbies/lojban/grammar/lojban.peg.txt
seem to difer more than I suspected at first.

I was going to suggest that just about every place where "NIhO+" was
used to be expanded into "NIhO+ I?" . I see that Chris's version chops
off a "-clause" from the end of lots of the rules concerning selma'o.
That's why I was getting confused if CMENE+ was doing the right thing
or not, the real rules use CMENE-clause+ which does.

So I quess I suggest that places that do a "NIhO-clause+" be changed
into a "NIhO-clause+ I-clause?"  or a "(NIhO-clause I-clause?)+"

Mostly it's so it a tiny bit more consistant with the implied " ni'o i
" that the rules in the magic words sections seems to imply exist for
"sa i" and "su" to work.

I could be totally crazy on my "ni'o i" suggestion, take with shaker of salt.
