You can boot up different versions of macOS and find out what's installed; I
did that before but I don't want to do it again right now.

GitHub recently changed their server configuration, and they now require
support for newer TLS protocols. For this reason, versions of git provided in
OS X 10.10 Yosemite and earlier can no longer connect to GitHub. Being able to
connect to GitHub is fairly important for MacPorts, so MacPorts 2.4.4 will
require MacPorts git on those older OS versions, when installing a port that
fetches using git.
Rainer wanted to always depend on MacPorts git for a different reason: his
changes in the vcs-fetch branch parse some git output, and the format of that
output changed in some git version. He knew what version of git he needed, but
he didn't want to figure out which versions of macOS came with which versions
of git, so he just always used the version from MacPorts. From my earlier
research into the GitHub TLS situation, I had already determined that the
version of git Apple provides in OS X 10.11 El Capitan and newer is greater
than the minimum version Rainer requires for vcs-fetch, so there is no need
change which git MacPorts uses further than what we're already changing for
2.4.4.
