Proposal: commit diff as input for changes to make on given repos

Consider adding an option which will parse a commit and compile a list changes to apply on all supplied repos.

For example, a list containing file modifications, simple word substitutions, commit message, branch name, and similar information could be inferred from the commit change(s).

Motivation: This abstraction could be applied in CI/CD pipelines to automatically propagate simple, predictable changes across many repos on a regular basis.
