+Previously, when a user fully completed a tag operation, they had to\r
+press space to begin entering another tag operation. This is\r
+different from, say, shell file name completion, which typically\r
+inserts a space after an unambiguous completion under the assumption\r
+that the user will want to enter more input.\r
+\r
+This patch tweaks `notmuch-read-tag-changes' to act more like shell\r
+file name completion: after an unambiguous tag completion, it now\r
+inserts a space, ready and waiting for another tagging operation from\r
+the user. This is backwards-compatible with old habits, since there's\r
+no harm in putting an extra space.\r
+---\r
+\r
+Just because of the context, this must be applied on top of the\r
+currently pending tag completion series\r
+id:"1382487721-31776-1-git-send-email-amdragon@mit.edu". The change\r
+itself should be otherwise independent.\r
