Document & test for cases where there are two remotes pointing to the same URL, and a background fetch & subsequent `git push --force-with-lease` shouldn't clobber un-updated references we haven't fetched. Some editors like Microsoft's VSC have a feature to auto-fetch in the background, this bypasses the protections offered by --force-with-lease & --force-with-lease=<refname>, as noted in the documentation being added here. See the 'Tools that do an automatic fetch defeat "git push --force-with-lease"' (<1491617750.2149.10.camel@mattmccutchen.net>) git mailing list thread for more details. Jakub Narębski suggested this method of adding another remote to bypass this edge case, document that & add a test for it.
