Log Message:
Backport "redundant pack" fix from the HEAD:  if you try to pack to a time
earlier than a .fs was previously packed to, the attempt shouldn't do
anything (except raise an exception).  It was trying to pack to the
earlier time anyway, but pack's reachability traversal can't work
correctly then due to the "missing" revisions in the gap between the
pack times, and the packed .fs could lose live data as a result.

+FileStorage
+-----------
+
+Fixed a serious bug in the new pack implementation.  If pack was
+called on the storage and passed a time earlier than a previous pack
+time, data could be lost.  In other words, if there are any two pack
+calls, where the time argument passed to the second call was earlier
+than the first call, data loss could occur.  The bug was fixed by
+causing the second call to raise a StorageError before performing any
+work.
