commit https://github.com/vim/vim/commit/8f08dab18df6dbf6c4b4973fd2d480e4bffb82d8 Author: Bram Moolenaar <Bram@vim.org> Date: Sat Nov 21 14:31:33 2015 +0100 patch 7.4.932 Problem: test_utf8 has confusing dummy command. Solution: Use a real command instead of a colon.

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