Can anyone take a look at this and tell me why, when given a string and a 
specified width for word wrapping, it sometimes trims the string way too 
short, or 3 or 4 characters too long? I've been frying my brain with this and 
I just can't get it straightened out:

this.FitMsg=function(text)
{
	var msg=text;
	if(console.strlen(msg)>=this.width) {
		while(console.strlen(msg)>=this.width) {
			var test_index=this.width;
			while(console.strlen(text.substring(0,test_index)) 
<this.width) 
			{
				if(msg.charAt(test_index)==" " || 
					msg.charAt(test_index+1)==" ") break;
				else if(msg.charAt(test_index)=="\1") {
					test_index++;
				}
				test_index++;
			}
			var push=this.RemoveSpaces(msg.substring 
(0,test_index));
			if(push.lastIndexOf(" ")>(this.width/2)) {
				test_index=push.lastIndexOf(" ");
				push=this.RemoveSpaces(push.substring 
(0,test_index));
			}
			this.messages.push(push);
			this.log.Log("adding text to msg buffer: " + push);
			msg=this.RemoveSpaces(msg.slice(test_index));
		}
		this.messages.push(this.RemoveSpaces(msg));
	}
	else this.messages.push(text);
	while(this.messages.length>this.height) 
		this.message_history=this.messages.shift();
	this.needs_update=true;
}
this.RemoveSpaces=function(text)
{
	while(text.indexOf(" ")==0) text=text.slice(1);
	return truncsp(text);
}


this is an excerpt from a larger piece of code, so some of the variables used 
in the functions are declared elsewhere.
