commit https://github.com/vim/vim/commit/da94fdf2588b3910d38e477a755748ce2c6d2e66 Author: Bram Moolenaar <Bram@vim.org> Date: Thu Mar 3 18:09:10 2016 +0100 patch 7.4.1482 Problem: "timeout" option not supported on ch_send*() and ch_eval*(). Solution: Get and use the timeout option from the argument.

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