I just thought it would be a stopgap until we get diff to support links natively. Obviously, when we get native diff support, 'log -p' will be able to show differences as well. As it turns out from my little experiment with cat-link, it's really easy to get native diff support, and I'm targeting that directly instead of a scripted solution. As for the unclearness issue, it's a little more complicated than that: a non-floating submodule could've previously been a floating one, or vice-versa. As of this moment, I'm only planning to show differences between link buffers. In the case when two consecutive commits change a link checkout_rev (where floating is set to 0), we can come up with something like the current diff.submodule = log. I see no cause to worry about the interface of that now. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
