* lisp/ob-ruby.el (org-babel-ruby-evaluate): Clean up the session code
and remove a superfluous `butlast'. Work around a problem in comint
where the first prompt in a session may be printed after the
evaluation has already started, thus producing a spurious line in
the output.
* testing/lisp/test-ob-ruby.el (test-ob-ruby/session-output-1,
test-ob-ruby/session-output-2 test-ob-ruby/session-output-3): Test
correct transfer of interpreter state across several session
invocations.
* lisp/ob-ruby.el (org-babel-ruby-evaluate): Temporarily disable the
irb prompt to ensure that the output is properly recognized using
the standard settings from inf-ruby and no extra settings in .irbrc
or other configuration files from Ruby. Remove superfluous
`comint-send-input' that produced a spurious empty line in output.
* testing/lisp/test-ob-ruby.el (test-ob-ruby/session-output): Remove
spurious emtpy line in expected output.
* lisp/ob-ruby.el (org-babel-ruby-evaluate):
set conf.echo=false for the duration of evaluation.
* testing/lisp/test-ob-ruby.el (test-ob-ruby/session-output): new test.
