You can also right click on the installer and select "Open" for a very similar dialog, but one that gives you the opportunity to run the installer anyway. > "README.txt" says I need "sudo mv /usr/bin/git /usr/bin/git-system".

Sounds like you're running afoul of El Capitan's new System Integrity Protection (SIP) [1]. The git commands you're seeing there are probably Apple's thin wrappers that are mostly meant to provide instructions on installing XCode, but SIP is stopping you from modifying the /usr directory (ah, Apple's Infinite Wisdom). There are discussions about working around SIP in the Apple forums [2] and Homebrew has some hints as well [3].
