* Added usleep contributed by Nicolas Pitre <nico@cam.org>
* tar wouldn't create directory entries that don't end in '/',
now it does (thanks to Avery Pennarun <apenwarr@worldvisions.ca>)
* tar has been completely rewritten, and tar creation and extraction
is now much better behaved.
* Several fixes from Pavel Roskin <pavel_roskin@geocities.com>:
- When `tail' fails to open a file it now exits.
- When `syslogd' is given the `-n' option it should still use
