What's new:
Solution to #432 by adding a commits and commits-file option.
--commits=<comma separated list of commits>
--commits-file=path to file containing a list of commits separated by newlines
NOTE
commits or commits-file should be used in favor of commit-to and commit-from as there is a reachability issue in that commit-from is not guaranteed to reach commit-to so you risk scanning many more commits than originally intended.
