Hrm, is it too heavyweight to autodetect and relieve the caller from the
burden of passing COL_ANSI?
Perhaps if you update utf8_strwidth() so that it takes <ptr, len> input
not NUL terminated string, you can do item_length like this, no?
cp = s;
width = 0;
while (1) {
ep = strstr(cp, "\033[");
if (!ep) {
width += utf8_strwidth(cp);
break;
}
utf8_strwidth_counted(cp, ep - cp);
... scan ep to skip the "\033[...;X"
cp = ep;
}
