sshx (and scpx) establish pseudo terminals, needed on MS Windows. See
the "-t -t" arguments of the ssh call.

There is `large-file-warning-threshold', which you could set to
nil. This is a global variable (not Tramp specific); don't know whether
it is needed to make it configurable just for Tramp.

However, copying a bunch of large files, I believe Tramp's scp is
preferable. This doesn't ask this question (I hope :-)
