int conf_string(struct menu *menu)
{
struct symbol *sym = menu->sym;
const char *def, *help;
while (1) {
printf("%*s%s ", indent - 1, "", menu->prompt->text);
printf("(%s) ", sym->name);
def = sym_get_string_value(sym);
if (sym_get_string_value(sym))
printf("[%s] ", def);
conf_askvalue(sym, def);
switch (line[0]) {
case '\n':
break;
case '?':
/* print help */
if (line[1] == '\n') {
help = nohelp_text;
if (menu->sym->help)
help = menu->sym->help;
printf("\n%s\n", menu->sym->help);
def = NULL;
break;
}
default:
line[strlen(line)-1] = 0;
def = line;
}
if (def && sym_set_string_value(sym, def))
return 0;
}
}
Above, variable "help" is not used and can be deleted.
You can send a patch which fixes it.
