GitHub wiki editing reload and re-apply

GitHub wikis while being edited by one user can have their changes become orphaned and un-save-able. The message might as well be a middle finger to all the work you did because the save button becomes disabled and it’s up to you to: 1) Figure out what the other editor changed 2) Remember all your changes and do the merge work yourself. This is standard fare for most non-collolabrative content managment systems, but this is GIT! The wiki portion of a project is literally backed by a git repository with limited features. If the wiki was a fully functional and separate repo this would have been handled by the existing merge/confict process that already exists on their git-web hybrid platform.
