After revising this to:

> sentence = [term ...[CU #]] bridi-tail | prenex sentence
> 
> bridi-tail = bridi-tail-1
>         [gihek [stag] KE # bridi-tail /KEhE#/ tail-terms] ...

> 
> bridi-tail-3 = selbri tail-terms | gek-sentence
> 
> gek-sentence = gek sentence gik sentence tail-terms

it yaccs without conflict, and seems pretty good to me.  It eliminates
the separate machinery of forethought sentence connection and forethough
bridi-tail connection, while still allowing for the latter via the rule
that a sentence may be a bridi-tail.

I have to think more on this, but tentatively I approve X4.
I will write up a formal change-control proposal tomorrow.
