[RFC] convert: fix --datesort
The problem is that previously commit.date was used for sorting, but it's a
string like "1 Jan xxx 2007", so it it wrong to use it for sorting.
Another problem is that why we are using depth for sorting -- I have no clear
answer -- it seems to be plain wrong.
This patch is just an RFC.
