commit https://github.com/vim/vim/commit/f3654827368e6204608036353a0360e9e7c21e02 Author: Bram Moolenaar <Bram@vim.org> Date: Fri Mar 4 22:12:23 2016 +0100 patch 7.4.1486 Problem: ":loadplugin" is not optimal, some people find it confusing. Solution: Only use ":packadd" with an optional "!".

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