commit https://github.com/vim/vim/commit/517ffbee0d5b7b46320726faaa330b61f54e867c Author: Bram Moolenaar <Bram@vim.org> Date: Wed Apr 20 14:59:29 2016 +0200 patch 7.4.1755 Problem: When using getreg() on a non-existing register a NULL list is returned. (Bjorn Linse) Solution: Allocate an empty list. Add a test.

#! /bin/sh
#
# which.sh -- find where an executable is located.  It's here because the
# "which" command is not supported everywhere.  Used by Makefile.
