Question about weird COPY syntax

Why is it that "DELIMITER", and "NULL" options are under [WITH] but
not under [CSV]. This seems at least slightly awkward.

Command: COPY
Description: copy data between a file and a table
Syntax:
COPY tablename [ ( column [, ...] ) ]
FROM { 'filename' | STDIN }
[ [ WITH ]
[ BINARY ]
[ OIDS ]
[ DELIMITER [ AS ] 'delimiter' ]
[ NULL [ AS ] 'null string' ]
[ CSV [ HEADER ] <-
Why not put them under this.
[ QUOTE [ AS ] 'quote' ]
[ ESCAPE [ AS ] 'escape' ]
[ FORCE NOT NULL column [, ...] ]
