peg.ebnf: Clean up EBNF: syntax.
...
The syntax for an EBNF parser is now ``EBNF: identifier string``. The
inline syntax went from [EBNF ... EBNF] to EBNF[[ ]], EBNF[=[ ]=], etc.
<EBNF looked for a main word, but this functionality is just EBNF[[ ]]
now.

syntax: removing #! as a comment character.
...
We don't need two types of comments and shebang (#!) is handled
natively by the lexer, so the original reason for #! is not valid.

More refactoring of EBNF
...
<EBNF .. EBNF> now produces a quotation that when called does the parsing
EBNF: foo ... ;EBNF creates a 'foo' word with stack effect (string -- result)
when called it parses the string and returns the result.

Update peg.pl0 to use range pattern syntax
...
This allows removing the words for ident and number, replacing them
with EBNF expressions.

More peg.pl0 additions
...
This parser is currently really ugly. The goal is to tidy up peg
so this parser looks more like the EBNF.
