commit https://github.com/vim/vim/commit/c970330676eaae7ba7cd05cfa46df5a413853ef9 Author: Bram Moolenaar <Bram@vim.org> Date: Sun Jan 17 21:49:33 2016 +0100 patch 7.4.1126 Problem: Can only get the directory of the current window. Solution: Add window and tab arguments to getcwd() and haslocaldir(). (Thinca, Hirohito Higashi)

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