* Added support for being a login shell, so things like
'-su' or '-sh' (stuff where argv[0][0]=='-') will now always
invoke the shell. Now you can use BusyBox as a login shell.
+ * ls.c now ignores '-g', since some ftp clients like that sort
+ of thing. Patch thanks to David Vrabel <dvrabel@arcom.co.uk>
