	* (main): don't be destructive to PATH -- this allows us to handle
	multiple arguments correctly.
	(long_format): new local var replaces global Show_Sizes.  Pass to
	search_dir().
	(search_dir): take long_format.
	Just invoke "ls -l ..." via system() to get long format; don't
	bother with all that `stat' stuff.  Why even reinvent the spoke,
	let alone the wheel?

	* which.c (search_dir): don't ever closedir() twice on the same
	dir.  Linux is newly sensitive to this.  Imagine that bug laying
	dormant all these years +shiver+.

        * which.c (main): include last elt of PATH in search, duh.
