If you used an +eval/* command from a non-emacs-lisp-mode buffer,
quickrun would prompt you for a program to evaluate the code with. If
you selected "emacs" the code would evaluate in an external Emacs
process and return displayed output (stdout).
This commit changes +eval/buffer, +eval/region, and
+eval/region-and-replace (and all the other +eval commands that use
them) to evaluate code in the current session instead.
