commit https://github.com/vim/vim/commit/95f096030ed1a8afea028f2ea295d6f6a70f466f Author: Bram Moolenaar <Bram@vim.org> Date: Thu Nov 10 20:01:45 2016 +0100 patch 8.0.0074 Problem: Cannot make Vim fail on an internal error.

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