Removing dead lines from vector files

[Malcolm Williamson]

Chris,
If you take these files into v.digit, and then immediately quit after getting
to the main menu, you will be offered the choice:
	Compress attributes? [n]
 
If you say "y", it will remove "dead" attributes automatically. This is 
probably the easiest way to do it.
