Subject: Patch 7.3.545
Fcc: outbox
From: Bram Moolenaar <Bram@moolenaar.net>
Mime-Version: 1.0

Patch 7.3.545
Problem:    When closing a window or buffer autocommands may close it too,
	    causing problems for where the autocommand was invoked from.
Solution:   Add the w_closing and b_closing flags.  When set disallow ":q" and
	    ":close" to prevent recursive closing.
Files:	    src/structs.h, src/buffer.c, src/ex_docmd.c, src/window.c
