The first two patches look mostly good to me. I have combined them
into one and made some minor changes. (a) Removed opt_two_phase and
related code from repl_gram.y as that is not required for this version
of the patch. (b) made some changes in docs. Kindly check the attached
and let me know if you have any comments? I am planning to push this
first patch in the series tomorrow unless you or others have any
comments.
