[PATCH] long prompts do not show vi search prefix

[Dylan Cali]

Hello,

For long prompts (127 chars or longer), vi search mode does not
display the [/?] prompt prefix.

I've included a small program below demonstrating the issue, and a
very small patch fixing it.

#include <stdio.h>
#include <readline/readline.h>

int main(void)
{
    rl_variable_bind("editing-mode", "vi");

    //char prompt[126]; /* displays search prefix */
    char prompt[127];   /* does not */

    int i;
    for ( i = 0; i < sizeof(prompt)-1; i++ ) {
        prompt[i] = 'x';
    }

    prompt[sizeof(prompt)-1] = '\0';

    while (1) {
        char *line = readline(prompt);
        add_history(line);
    }
}

Thank you!
