Indeed. It should probably be something like:

if (!(quote = strchr(buf, '\"'))) {
    if ((eol_pnt = strchr(buf, '/')) || (eol_pnt = strchr(buf, '}'))) {
        *eol_pnt = '\0';
    }
    return buf;
} else {
    if ((eol_pnt = strchr(quote + 1, '\"'))) {
        *eol_pnt = '\0';
    }
    return quote + 1;
}
