My basic understanding is that license (usually?) applies to just the code. There is no concept of "history" or "snapshot" pertaining to the code itself. Such constructs only exist with regard to the process of development, about which the code license does not care. Otherwise, every keystroke must be recorded and published to ensure compliance, at which point, the license is ridiculous and unenforceable.
