From a3736e97a6ca517c2cd7d3d93a8f2ef86e39e5b5 Mon Sep 17 00:00:00 2001 From: eregon Date: Sun, 7 May 2017 12:04:49 +0000 Subject: Add in-tree mspec and ruby/spec * For easier modifications of ruby/spec by MRI developers. * .gitignore: track changes under spec. * spec/mspec, spec/rubyspec: add in-tree mspec and ruby/spec. These files can therefore be updated like any other file in MRI. Instructions are provided in spec/README.
