Rather than fetching the entire repository history, limit the fetch depth to commits in the last 4 weeks. If a branch was branched longer than 4 weeks ago, it seems reasonable to require it to be rebased before it can be reviewed. At the current rate of development, this reduces the bandwidth needed for git pulls in the initial code checks from 73MB to 9MB. Signed-off-by: Philip Withnall <withnall@endlessm.com>
