commit https://github.com/vim/vim/commit/8dd3a43d75550e9b5736066124c97697564f769e Author: Bram Moolenaar <Bram@vim.org> Date: Mon Aug 1 20:46:25 2016 +0200 patch 7.4.2142 Problem: Leaking memory when redefining a function. Solution: Don't increment the function reference count when it's found by name. Don't remove the wrong function from the hashtab. More reference counting fixes.

" 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.
