In anticipation of checking commit-graph file contents against the object database, create parse_commit_internal() to allow side-stepping the commit-graph file and parse directly from the object database.
Nitpick/Bikeshed painting: do we have any naming convention for such functions (*_internal() here)?
Due to the use of generation numbers, this method should not be called unless the intention is explicit in avoiding commits from the commit-graph file.
Looks good to me, except for some stray whitespace changes in the patch.

Stray empty line, though I think it may improve readability of the code by using two empty lines between separate functions. But to be consistent with the rest of the file, there shouldn't be this extra empty line.

All right.

All right; if it is internal details of implementations, I don't mind this slightly cryptic "1" as the value of last parameters.
