Log Message:
When trying to print a help message while editing a multiline entry, print
move down enough so that the error message does not get printed on top of
the newline from Yuishiro NAITO. Example program:

#include <stdio.h>
#include <histedit.h>

char *
prompt(EditLine *el)
{
        return "(config) ";
}

static unsigned char
help(EditLine *el, int ch)
{

        printf("\n");
        printf("aaa:\n");
        printf("bbb:\n");
        printf("ccc:\n");
        printf("ddd:\n");

        return CC_REDISPLAY;
}

int
initialize(EditLine **ret)
{
        EditLine *el;

        if ((el = el_init("sample", stdin, stdout, stderr)) == NULL)
                goto error;

        el_set(el, EL_PROMPT, prompt);
        el_set(el, EL_EDITOR, "emacs");
        el_set(el, EL_ADDFN, "help", "", help);
        el_set(el, EL_BIND, "?", "help", NULL);

        *ret = el;
        return 0;

error:
        el_end(el);
        *ret = NULL;
        return -1;
}

int
main(int argc, char *argv[])
{
        EditLine *el;
        const wchar_t   *cmd;
        int len;

        if (initialize(&el) < 0) {
                printf("initialize failed\n");
                return 1;
        }

        while ((cmd = el_wgets(el, &len)) != NULL) {
                printf("ok\n");
        }

        el_end(el);

        return 0;
}
