commit https://github.com/vim/vim/commit/a803c7f94070f94b831fdfd1984f288c8b825b5d Author: Bram Moolenaar <Bram@vim.org> Date: Fri Jan 15 15:31:39 2016 +0100 patch 7.4.1092 Problem: It is not simple to test for an exception and give a proper error message. Solution: Add assert_exception().

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