commit https://github.com/vim/vim/commit/6835dc61aebca2b602d85a9d63c449ace58683b4 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Jul 24 17:33:05 2016 +0200 patch 7.4.2100 Problem: "cgn" and "dgn" do not work correctly with a single character match and the replacement includes the searched pattern. (John Beckett) Solution: If the match is found in the wrong column try in the next column. Turn the test into new style. (Christian Brabandt)

" 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 utf8 'encoding'.  Setting 'encoding' is already done in
" runtest.vim.  Checking for the multi_byte feature is in the individual
" files, so that they can be run by themselves.
