The function that does the main pty setup is now called pty_backend_create(), and has an API better suited to uxpty in particular than the standard backend_init() virtual constructor. It leaves off a load of standard parameters to backend_init() which aren't really relevant to this backend, and it adds the 'argv' parameter to pass in a split-up command line, which is unique to it. The old creation function still exists, as a tiny wrapper that calls the new pty_backend_create. And that version still gets the argv parameter from the process-global variable pty_argv[], so the call sites in pterm haven't had to change for this. This will make it possible to instantiate a pty backend directly from the SSH server code, without having to do anything really excessively cumbersome to pass in a subcommand in the form of pre-split argv. (And I'll add a few more specialist parameters to the new function shortly.)
