Just to clarify: what happens when you type :!stty -a from inside ghci
immediately after entering ghci?

I suspect this is a problem with libedit, since HEAD replaced readline
with it it between 6.8 and 6.10. Do you know of any other programs on
your machine that use libedit and whether they have the same issue?
Otherwise, would it be possible for you to compile the following C program
(with {{{gcc -ledit}}}) and check its behavior inside the xterm?
{{{
#include <stdio.h>
#include <editline/readline.h>
int main(void) {
char *result;
rl_initialize();
result = readline("enter:");
printf("%s\n",result);
return 0;
}
}}}
