To be followed by tests and `npm run build`, obviously!

Turns out they're not actually needed, because the implementation of
"finding all commits" just iterates over the lines of the `git log`
output, anyway - no need to actually traverse the tree.
I am _reasonably_ sure this means that it's no longer a pre-requisite
that the source repo has linear history, either. If I discover during
adding tests that that actually is the case, I'll re-add that note.
