Just to clarify: real git doesn't actually do any authentication on
its own, it just depends on ssh - it executes an external program to
open the connection. So you get all the configurability that ssh has.
Per-site keys, per-site user-names etc etc.

libgit2, in contrast, wants to do everything by hand in C. It uses
libssh2, but that isn't the same thing at all as executing the ssh
program.
