Merge branch 'cc/receive-pack-limit'
An incoming "git push" that attempts to push too many bytes can now be rejected by setting a new configuration variable at the receiving end. * cc/receive-pack-limit: receive-pack: allow a maximum input size to be specified unpack-objects: add --max-input-size=<size> option index-pack: add --max-input-size=<size> option
