[Plugin: Link Indication] rel="external" instead of target="_blank"

I’ve changed the code starting at line 212 in order to substitute the target attribute by the rel=”external”. As the author say the target attribute isn’t W3C valid, so why not get rid of it definitely.

/**********************
* For external links, we apply target="_blank" (if there is not already a target attribute in the anchor tag)
*********************/
$targetblank = '';
if ( (substr($linktype, 0, 8) == 'external') && ($this->g_opt['mwli_targetblank'] == '1') ) {
//if ( (strpos($matches[1] . $matches[6], 'target=') === false) ) {
if ( ! preg_match("/rel=[\"\'].*?external.*?[\"\']/i", $matches[1] . $matches[6] ) ) {
// there is no target=, so we add target="_blank"
//$targetblank = 'target="_blank"';
$targetblank = 'rel="external"';
}
}

If Someone needs desperately to open a external link in another window, she could add a Jquery like:

<script>
$(function() {
$(‘a[rel*=external]‘).click( function() {
window.open(this.href);
return false;
});
});
</script>
