Similarly for stdin, "lua - <1.luac" fails even though "lua 1.luac" works.

Also, should io.stdout and io.stdin open in ASCII or binary mode?
Binary is more useful, and ASCII files can be processed most generally
in binary mode.  To implement something like netpbm image filters, you
will need binary stdin/stdout.
