Re: [RFC/PATCH] connect: add GIT_SSH_{SEND,RECEIVE}{,_COMMAND} env variables

I get that you may have two different keys to go with two different
identities on a remote system. But I'm not sure I understand why
"sending" or "receiving" is the right way to split those up. Wouldn't
you also sometimes want to fetch from repository X? IOW, wouldn't you
want to tie identity "A" to repository "X", and "B" to repository "Y?

So now I just have a GIT_SSH_COMMAND that dispatches to different keys
depending on the operation, as noted in the commit message, and I can
assure you that without that logic it doesn't work.

You mentioned host aliases later, which is the solution I've seen in the
wild. And then you can map each remote to a different host alias.

Yup, I do agree that it is exactly the established solution for this
kind of situation.
