2533 # - 24 bytes for every record,
2534 # * 4 bytes for the integer representing an SVN revision number
2535 # * 20 bytes representing the sha1 of a git commit
2536 # - No empty padding records like the old format

2538 # increase monotonically

2541 # viewing or editing, should the need ever arise.
