patch 8.2.0412: MS-Windows: cannot use vimtutor from the start menu Commit: https://github.com/vim/vim/commit/37f471df6ee422beb4d08ee4ccda35f8279e3bb7 Author: Bram Moolenaar <Bram@vim.org> Date: Thu Mar 19 17:13:40 2020 +0100 patch 8.2.0412: MS-Windows: cannot use vimtutor from the start menu Problem: MS-Windows: cannot use vimtutor from the start menu. Solution: Better check for writable directory. Use the right path for the executable. (Wu Yongwei, closes #5774, closes #5756)

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