Is there any reason to switch to another directory? Why doesn't Emacs just ignore that the current directory has been removed (and report errors only when an access to it is really needed)? Note that the current directory can also be removed after Emacs is started, so I expect that Emacs already supports cases like that. In the init_buffer() function, it seems that pwd is used only for: bset_directory (current_buffer, make_unibyte_string (pwd, len)); If the current directory has been removed, couldn't Qnil be used (or, if not possible, ".")? Note: this is the first time (well, almost) I look at the Emacs C source. -- Vincent Lefèvre - Web: 100% accessible validated (X)HTML - Blog: Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
