That's a beginning, thanks. But it needs more work, IMO:
. the cons cell case hints on a possible return value of STARTKEYFUN,
AFAIU, but the text doesn't say so
. the case of STARTKEYFUN being nil is another use case for what
PREDICATE must cope with, and the text should say so
. the text about ENDKEYFUN should also be augmented, IMO
. the description of PREDICATE should reference this text in some
useful way

What collation would you like to support, and in what form?
