bug#7002: Emacs initializes the alternate screen twice

[emacs-bugs-7626]

When a console-mode Emacs initializes its terminal, it sends the escape
sequence to switch to the alternate screen twice. This causes problems
when running under screen (and maybe other terminal programs as well):
exiting or suspending Emacs completely clears the screen. I have
attached a patch that fixes this.

Thanks, installed in the emacs-23 branch.

In the future, please include a name of some sort in your
communications, since we need it to maintain accurate
copyright information.

Sorry about that. I don't send much email from my alternate addresses,
and forgot to include my name on that one.
