pwd (eshell) in Emacs 24.0.92

[Rajanikanth Jammalamadaka]

Hi

I built Emacs 24.0.92 on Suse Linux 10.2 (64-bit). When I start up an eshell (using M-x eshell)
and type pwd, it displays the current directory but it does not show me the prompt back.
I have to press the return key again for emacs to show me the prompt.

Did anybody else see this?

Also, what is the best way to tell emacs to not make backup files?

Thanks,
Raj
