Since non-Cygwin executables don't understand ptys, they think they are
dealing with a pipe and so they buffer their output.  It's not specific
to OpenSSH.  You'd see the same issue running these programs under xterm
or mintty.  I personally wouldn't define anything about this particular
issue as a "lost cause" but YMMV.  Quite some time ago there was an attempt
to smooth out this issue with a utility call ttyfier but it had it's issues
and has pretty much disappeared.  I don't know of any other aids out there,
though that doesn't mean there isn't something .  The only things I can
suggest are that you make sure there's not some Cygwin utility that does what
you want or that you write something that does.
