commitctx: document a fast path in _filecommit

This block cut off a lot of logic, documenting the why and how seems useful to
future reader.

This is part of a larger refactoring/cleanup of the commitctx code to clarify
and augment the logic gathering metadata useful for copy tracing. The current
code is a tad too long and entangled to make such update easy. We start with
easy and small cleanup.
