I think it's a fundamentally hard problem to fix, but it may be that the 
fix is to give hints about command line options and in particular the time 
fuzz thing to try.

So maybe just _detection_ logic in cvsps, along with a warning like

	"time fuzz is 600 seconds, and the time difference between the two
	 commits of this file was 431 seconds. You may want to try a lower
	 -z argument"

or something.

It might also be possible to try to sort all the names by date of commit
first, and see if they "bunch up" into groups of low fuzz with much bigger 
fuzz in between groups..
