At least for me, even if it came out larger than the RCS files, I don't 
care - so long as we're only talking about disk space, not netsync.  In 
the days of cheap 300GB disks, normal code is never going to take up 
enough space that I really notice.  We're still using normal DSL lines, 
though (and some people are still using modems), so netsync bandwidth 
*is* interesting.

The one place I can think of where this strategy doesn't work is for 
people doing revision control of 600MB .iso files, or something 
similarly large.  Those people would probably prefer the cost of an 
additional delta to be as small as possible.  This is clearly not the 
normal case, though - and even for those people, their deltas might be 
small, even though their files are large.
