two SUJ requests

hi there. i really love working with SUJ and haven't had a single
panic or problem at all with it. these two requests are rather minor,
but it would be nice if you could think about adding them:

1. it would be nice to have the /.sujournal file set to a proper
creation/access/modify timestamp instead of unix timestamp 0 (1 jan
1970). just like with snapshot files. that way one could keep track of
when SUJ was enabled e.g.

2. the tunefs(8) manual states that the minimum size of the journal
using the -S switch is 4mb. it would be nice to also have the manual
state the default size of the journal.

that's it really. ;)

thanks.
