commit https://github.com/vim/vim/commit/d29459baa61819e59961804ed258efac5733ec70 Author: Bram Moolenaar <Bram@vim.org> Date: Fri Aug 26 22:29:11 2016 +0200 patch 7.4.2263 Problem: :filter does not work for many commands. Can only get matching messages. Solution: Make :filter work for :command, :map, :list, :number and :print. Make ":filter!" show non-matching lines.

Test for Bufleave autocommand that deletes the buffer we are about to edit.
