patch 8.2.4007: session does not restore help buffer properly Commit: https://github.com/vim/vim/commit/8e7d9db32b53ca2b1cb7570d2042860bcd1e943f Author: matveyt <matthewtarasov@gmail.com> Date: Wed Jan 5 14:01:30 2022 +0000 patch 8.2.4007: session does not restore help buffer properly Problem: Session does not restore help buffer properly when "options' is missing from 'sessionoptions'. Solution: Use a ":help" command to create the help window. (closes #9475, closes #9458, closes #9472)

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