*shell* buffer in GNU Emacs 23.0.0 has faulty terminal control

[Peter Dyballa]

Hello!

Launching GNU Emacs 23.0.0 with -Q I create a *shell* buffer (tcsh is  
my login shell) and run git to clone some repository (X11R7.1). While  
git runs it produces progress output. Different from the behaviour of  
GNU Emacs 22.0.50's *shell* buffer there is /not/ one spot  
overwritten with the new text, but the new text is added on a new  
spot. In the end the 23.0.0 *shell* buffer has a contents like:

A similiar effect happens in GNU Emacs 23.0.0 when Fink fetches  
(presumingly with curl) an open software archive.
