No, because you sometimes want to know what 2.6.39++ is and what 3.0--
is.

For instance, to upgrade from 2.6.37.2 to 3.1.2, ketchup will want to
download, cache, and apply:

patch-2.6.37.2 (reversed!)
patch-2.6.38
patch-2.6.39
patch-3.0 ?? <- hopefully Linus will make a delta against 2.6.39!
patch-3.1
patch-3.1.2
