[PATCH (MINGW) Resend] Windows: Make OpenSSH properly detect tty detachment.

[Alexander Gavrilov <angavrilov@gmail.com>]

Apparently, CREATE_NO_WINDOW makes the OS tell the process
that it has a console, but without actually creating the
window. As a result, when git is started from GUI, ssh
tries to ask its questions on the invisible console.

This patch uses DETACHED_PROCESS instead, which clearly
means that the process should be left without a console.
The downside is that if the process manually calls
AllocConsole, the window will appear. A similar thing
might occur if it calls another console executable.

	This patch appears to have been overlooked, so I	resend
	it just in case. It fixes a long standing problem in msysgit.
