[lojban] more errors in EBNF rules (and other comments)

[MorphemeAddict@wmconnect.com]

In looking through the wiki list of grammar rule typos in the Red Book, I noticed they all had large spaces where the missing "|" was supposed to be, so I looked through the whole EBNF grammar for more large spaces, and I found two more, which I then compared with the YACC version:

1) fragment-20 should have a "|" before NA.

2) sumti-tail-111 should have a "|" between the first "sumti-tail-1" and the second "relative-clauses".

3)  Another difference I noticed is that where YACC has rules for

sumti_90
sumti_A_91
sumti_B_92
sumti_C_93
sumti_D_94
sumti_E_95
sumti_F_96
sumti_G_97

EBNF has

sumti90
sumti-191
sumti-292
sumti-393
sumti-494
sumti-595
sumti-697

with no sumti-7 rule and no rule numbered 96.  Perhaps sumti-5, sumti-6, and sumti-7 were combined.  Here is what I think they should be:

sumti-595 = sumti-6 [relative-clauses] | quantifier selbri gap [relative-clauses]

sumti-696 = [quantifier] sumti-7

sumti-797 = {text of current rule sumti-697}

4)  It looks like rule sumti-292 should be

sumti-292 = [sumti-2 joik-ek] sumti-3

instead of (the apparently equivalent)

sumti-292 = sumti-3 [joik-ek sumti-3]...

Why was so much alteration made to the EBNF version when a straightforward rewrite of the YACC would have been clearer?
