commit https://github.com/vim/vim/commit/df48fb456fb6bf63d94cad9b302ff01d8ee8d311 Author: Bram Moolenaar <Bram@vim.org> Date: Fri Jul 22 21:50:18 2016 +0200 patch 7.4.2090 Problem: Using submatch() in a lambda passed to substitute() is verbose. Solution: Use a static list and pass it as an optional argument to the function. Fix memory leak.

" 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.
