+(i.e., the date format used in mail and news headers, and returned by
+the function @code{message-make-date} by default). The data should be

+It is okay for this function to return `too many' groups; some backends
+might find it cheaper to return the full list of groups, rather than
+just the new groups. But don't do this for backends with many groups.
+Normally, if the user creates the groups herself, there won't be too
+many groups, so nnml and the like are probably safe. But for backends
+like nntp, where the groups have been created by the server, it is quite
+likely that there can be many groups.
