[PATCH] LALR Parser Documentation Fix

[Noah Lavine <noah.b.lavine@gmail.com>]

The documentation for the LALR parser currently says that the
tokenizer procedure passed to the parser should be a unary procedure
taking a port, but the documentation at
http://code.google.com/p/lalr-scm/wiki/ParserDefinition says it should
be a thunk. The following patch fixes this:
