	* defs.h (directory_switch): Add prototype.
	* main.c (captured_main): Use directory_switch() instead of
	directory_command() to add directories from the -d switch.
	* source.c (directory_switch): New function.
	(add_path): Use buildargv() to parse spaces in filenames properly.
	Strip multiple trailing '/' rather than just one.
