    Unix Pageant: -T option, tying lifetime to controlling tty.
    
    This is intended to be a useful mode when you want to run an ssh agent
    in a terminal session with no X11 available. You just execute a
    command along the lines of eval $(pageant -T), and then Pageant will
    run in the background for the rest of that terminal session - and when
    the terminal session ends, so that Pageant loses its controlling tty,
    it will take that as the signal to shut down. So, no need to manually
    kill it, and unlike 'pageant --exec $SHELL', you can also do this half
    way through a session if you don't realise until later that you need
    an SSH agent, without losing any shell command history or other shell
    context that you've accumulated so far in the session.
    
    Unfortunately, I haven't been able to find any reliable way to
    actually implement this -T mode, short of having Pageant wake up at
    regular intervals and try to open /dev/tty to see if it's still there.
    I had hoped that I could arrange to reliably get SIGHUP, or select on
    /dev/tty for exceptional conditions, or some such, but nothing I've
    tried along those lines seems to work.

    Const-correctness in key-loading functions.
    
    The passphrase parameter should be a const char *.

    Pageant: factor out cross-platform parts of add_keyfile().
    
    I've now centralised into pageant.c all the logic about trying to load
    keys of any type, with no passphrase or with the passphrases used in
    previous key-loading actions or with a new user-supplied passphrase,
    whether we're the main Pageant process ourself or are talking to
    another one as a client. The only part of that code remaining in
    winpgnt.c is the user interaction via dialog boxes, which of course is
    the part that will need to be done differently on other platforms.

    Unix Pageant: move handling of --exec arguments.
    
    Now --exec instantly terminates option processing, by treating
    everything after it as the command. This means it doesn't matter if
    the --exec command word looks like another option, and it also means
    we can simplify the handling of real non-option argument words, when I
    get round to adding some for loading keys.
