after discussion and argument and nit-picking and revision
What happens if I already submitted the pull request and then commit a fix to my patch, so there are now 2 commits in that pull request. Am I supposed to squash the commits into one? Do I need to re-submit my pull request afterwards?
You do not have to resubmit the pull request. Squash the commits into one, and then "git push --force" to "rebase" the branch.
