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
