commit: avoid parent list buildup in clear_commit_marks_many()
clear_commit_marks_1() clears the marks of the first parent and its first parent and so on, and saves the higher numbered parents in a list for later. There is no benefit in keeping that list growing with each handled commit. Clear it after each run to reduce peak memory usage.
