commit https://github.com/vim/vim/commit/e8aee7dcf9b12becff86e8ce1783a86801c5f9f6 Author: Bram Moolenaar <Bram@vim.org> Date: Tue Apr 26 21:39:13 2016 +0200 patch 7.4.1793 Problem: Some character classes may differ between systems. On OS/X the regexp test fails. Solution: Make this less dependent on the system. (idea by Kazunobu Kuriyama)

" A series of tests that can run in one Vim invocation.
" This makes testing go faster, since Vim doesn't need to restart.

" These tests use latin1 'encoding'.  Setting 'encoding' is in the individual
" files, so that they can be run by themselves.
