[PATCH] LALR Parser Documentation Fix

[PATCH] LALR Parser Documentation Fix

[Noah Lavine]

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:

Good catch; applied, thanks!

BTW, next time please send your patch in “git format-patch” format, with
a suitable commit log.

Thanks,
Ludo’.
