If anything, fast-import would want to allow a deeper depth than normal, since (IIRC) its delta chains are always completely linear. Whereas in a real pack, if we decide not to make a delta off the 50th item in a chain, we usually find the 48th or 49th, and end up with a bushier graph. It probably doesn't matter that much, though, as you'd really want to `repack -f` afterwards if you care about getting good deltas. And one base object every 50 versions is probably fine for keeping the initial pack manageable. > --- > Documentation/git-fast-import.txt | 2 +- > fast-import.c | 2 +- > 2 files changed, 2 insertions(+), 2 deletions(-) Patch itself looks obviously correct. -Peff
