BTW @epayet, you can just push additional commits to an existing PR branch on GitHub and those will be included in the eventual change set that would get merged into master.
No need to create a new pull request for these incremental-edit scenarios.
This is especially useful for any changes that require a few iterations during the pull-request process.
Thanks for the submission.
