Simon Tatham 514796b7e4 Add an interactive anti-spoofing prompt in Plink.
At the point when we change over the seat's trust status to untrusted
for the last time, to finish authentication, Plink will now present a
final interactive prompt saying 'Press Return to begin session'. This
is a hint that anything after that that resembles an auth prompt
should be treated with suspicion, because _PuTTY_ thinks it's finished
authenticating.

This is of course an annoying inconvenience for interactive users, so
I've tried to reduce its impact as much as I can. It doesn't happen in
GUI PuTTY at all (because the trust sigil system is used instead); it
doesn't happen if you use plink -batch (because then the user already
knows that they _never_ expect an interactive prompt); and it doesn't
happen if Plink's standard input is being redirected from anywhere
other than the terminal / console (because then it would be pointless
for the server to try to scam passphrases out of the user anyway,
since the user isn't in a position to enter one in response to a spoof
prompt). So it should only happen to people who are using Plink in a
terminal for interactive login purposes, and that's not _really_ what
I ever intended Plink to be used for (which is why it's never had any
out-of-band control UI like OpenSSH's ~ system).

If anyone _still_ doesn't like this new prompt, it can also be turned
off using the new -no-antispoof flag, if the user is willing to
knowingly assume the risk.

PuTTY README
============

This is the README file for the PuTTY installer distribution. If
you're reading this, you've probably just run our installer and
installed PuTTY on your system.

What should I do next?
----------------------

If you want to use PuTTY to connect to other computers, or use PSFTP
to transfer files, you should just be able to run them from the
Start menu.

If you want to use the command-line-only file transfer utility PSCP,
you will probably want to put the PuTTY installation directory on
your PATH. On Windows 7 and similar versions, you can do this at
Control Panel > System and Security > System > Advanced system
settings > Environment Variables.

Some versions of Windows will refuse to run HTML Help files (.CHM)
if they are installed on a network drive. If you have installed
PuTTY on a network drive, you might want to check that the help file
works properly. If not, see http://support.microsoft.com/kb/896054
for information on how to solve this problem.

What do I do if it doesn't work?
