I'd really like to fix ketchup to behave sanely in late -rc stages:
going from -rc6 to -rc8 is possible using two downloads through --rc7
(like 100KB?)  instead of two big ones through full release (like
10MB).

But first step is --only-dl option -- when you want to cache the
needed patches but not apply anything yet.

Please apply,
									Pavel
