Protected branch regex also prevents creating new branches
I presented in GLU about the new protected branch regex permissions. There was a question about whether the regex format prevented the creation of a new branch by unauthorized users or if it's just existing branches. I'm happy to say that after testing it does prevent creating new branches if they match the regex.
This is great and we should add documentation accordingly. Also, we should consider adding a bullet point on the Protected Branches
page to highlight this fact.
