Mike covered the details, but the high-level is this: start-commit
_cannot_ have access to all the data that pre-commit can, for the simple
reason that the server receives some data from the client after
start-commit but before pre-commit. (And, naturally, if it weren't that
way, we would deprecate one of the hooks and subsume it into the other)

Specifically, start-commit is before the client uplods all the file
contents modifications.
