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.

" This is used only when the +eval feature is available.
if executable("cmd.exe")
   set shell=cmd.exe
endif
