commit https://github.com/vim/vim/commit/33a80eeb859a78ba93432da6fa585786cfd77249 Author: Bram Moolenaar <Bram@vim.org> Date: Mon Sep 5 21:51:14 2016 +0200 patch 7.4.2331 Problem: Using CTRL-X CTRL-V to complete a command line from Insert mode does not work after entering an expression on the command line. Solution: Don't use "ccline" when not actually using a command line. (test by Hirohito Higashi)

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