Minor doc fix. Added several bugs to the todo list. Fixed the way init

scans /etc/inittab entries so that commands can contain ":"s.

 	* zcat now works (wasn't working since option parsing was broken)
 	* Renamed "mnc" to the more correct "nc" (for netcat).
 	* Makefile intelligence updates
+	* Changed the way init parses /etc/inittab entries to avoid problems
+	    with commands that contain colons in them.  Fix thanks to

  - 'grep foo$ file' doesn't work
  - 'grep *foo file' segfaults
  - ps dirent race bug (need to stat the file before attempting chdir)

+	rm -f
