Mississippi -> Miiippi

Additional information.

This weird behavior can only be observed in an xterm with bash.
If I invoke it by "xterm -e tcsh" then no problem. If I do
"xterm -e bash" (or without -e bash) then no 's' allowed at
the prompt. I can't type nor paste.

The stdout still works so that I do see all the 's'es in
a command output. But not at the shell prompt. The bash shell
prompt.
