entries x and y in the list produced by the sort call, if x's
bfp = y's bfp, x should come before y if x's efp < y's efp.
The idea is that enclosing entries should always come later
in the list. this affects only languages where two expressions
can start at the same character position.
pdhtml.ss
expanded capability of ez-grammar with support for simpl
parsing of binary operators w/precedence and associativity
and automatically generated markdown grammar descriptions.
ez-grammar-test.ss now also doubles as a test of pdhtml for
algebraic languages.
