Hmmm.  Well, I'm planning on mostly using it for full updates, so I'll
leave the brokenness for someone who needs correct behavior for partial
updates (which may well be me, three weeks from now :).

If partial updates contained subdirectories as well, there wouldn't be
any broken behavior to fix.

If all wraps contained all requisite directories, it wouldn't matter;
as several people have pointed out the ctime for directories is not
constant, so it wouldn't be a fix regardless.  And anyway I wouldn't
expect the wrap format to change for this problem when there is an
easier, more elegant, and backwards-compatible fix.
