Patch 7.2.241
Problem:    When using a combination of ":bufdo" and "doautoall" we may end up
	    in the wrong directory. (Ajit Thakkar)
	    Crash when triggering an autocommand in ":vimgrep".  (Yukihiro
	    Nakadaira)
Solution:   Clear w_localdir and globaldir when using the aucmd_win.
	    Use a separate flag to decide aucmd_win needs to be restored.
Files:	    src/fileio.c, src/globals.h, src/structs.h
