All of the things that were not in the "master" branch were either cooked long enough in "next" without causing problems (e.g. insanely fast rename detector or true built-in diff) or isolated in a specific subsystem (e.g. tar-tree and svnimport).
So I am clearing the deck to prepare for a 1.3.0. Remaining wrinkles, if any, will be ironed in the "master" branch.
