+This is v2 of id:1381185201-25197-1-git-send-email-amdragon@mit.edu.\r
+It fixes several comments from Mark and Jani. This has been rebased\r
+on top of the tag completion changes, so doing * from a large search\r
+buffer will no longer crash. Hence, this series depends on the\r
+(currently pending) series in\r
+id:1382487721-31776-1-git-send-email-amdragon@mit.edu.\r
+\r
+This version does not address what happens when you * on a search\r
+buffer that's still filling. With this series, it will apply to all\r
+messages that have appeared when the user finishes entering tag\r
+changes. This isn't ideal, but this seems pretty obscure and I'm not\r
+sure what the right answer is, so I'm punting it to the future.\r
+\r
+Another thing that may be worth changing in a follow-up is what\r
+messages * applies to. Currently, * applies *only* to matched\r
+messages, not all threads in the search, which I think was an accident\r
+of implementation. This series retains that behavior, but opens up\r
+the possibility of applying to all threads instead. I think that\r
+would be much more consistent and less surprising behavior.\r
+\r
+An approximate diff from v1 is below. This diff is prior to rebasing,\r
+since the post-rebase diff is not useful.\r
