That's it.

What the stock Emacs' emacsclient does today:

 - Try to connect with the Emacs server.
 - If it can connect, great, that's all folks.
 - If it cannot, and there's an alternate editor, start that editor
(it could be Emacs), passing it the file arguments, etc.
 - Otherwise fail.

What would be nice (and Lennart's EmacsW32 emacsclient more or less
does, I think):

 - Try to connect with the Emacs server
 - If it can connect, great, that's all folks
 - If it cannot, start Emacs and wait until Emacs starts the server
 - Retry connecting with Emacs
 - If it can connect, great.
 - If not, start an alternate editor if defined (passing the file args, etc.)
 - Otherwise fail

The difference is that, in the first case, emacsclient starts the
alternate Emacs and then finishes. It does not maintain a connection
with Emacs or waits until the user signals (from inside Emacs) that
he's done with the buffer/file. That is not good when the one calling
emacsclient was not the user, but a process that starts emacsclient to
get a user-edited file (for example, a commit log) and considers that
emacsclient finishing means that the user-edited file is ready to be
