commit https://github.com/vim/vim/commit/b8d4905592fc26fcd09180d7d6bfefd899f2f6c6 Author: Bram Moolenaar <Bram@vim.org> Date: Sun May 1 14:22:16 2016 +0200 patch 7.4.1814 Problem: A channel may be garbage collected while it's still being used by a job. (James McCoy) Solution: Mark the channel as used if the job is still used. Do the same for channels that are still used.

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