Ah, that's a comfort.  Setting GIT_SSH_VARIANT would avoid this
autodetection code and is the recommended thing to do.

That said, we can't go back in time and update everyone's tools to do
that (e.g. there is not even a release of repo with [1] out yet), so
this is still considered a regression and I'm glad you found it.
