OK, so maybe I am missing something really basic, but this cropped up today when I was creating a directory index for publications on one of our sites.
I created a view using the default glossary view as a reference. When I first created the view and added my filters for Published and Node Type I noticed that the preview list had no sort order so I added Sort By: Node Title and previewed again... was surprised to see something along the lines of:

Now, I can tell the editors to make sure they don't do things like this, but it would be nice to handle it programmatically by running a trim() on $node->title... problem is that I have never hooked a core function before so I'm not entirely sure where to do that. I just need a pointer to which function to hook into in order to do the trim. I've looked at node_validate and node_save, but I can't see where the title is being validated as not empty (which would be a good place to start).
I also don't particularly want to have a complete copy of the core function code in my module, is there a way of forcing the hook to perform it's changes to the node and then call the core function?
I usually like to work these things out myself but I am a bit stumped and any help would be greatly appreciated :)

Untested code..
<?php
mymodule_nodeapi(&$node, $op, $a3 = NULL, $a4 = NULL) {
switch($op){
case 'presave' :
$node->title = trim($node->title);
break;
}
}
?>
