commit https://github.com/vim/vim/commit/3ef5bf7d459d6b8a21aaefc80f65448f5a7aa59f Author: Bram Moolenaar <Bram@vim.org> Date: Wed Jun 15 22:41:31 2016 +0200 patch 7.4.1941 Problem: Not all quickfix tests are also done with the location lists. Solution: Test more quickfix code. Use user commands instead of "exe". (Yegappan Lakshmanan)

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