[WASTE-list] Line numbers with wrapping

[Gmail]

I found that when using WEGetLineRange it will return the line number  
based on the actual amount of lines in the document, instead of based  
off line breaks. I'm trying to implement a system where line numbers  
are drawn in the gutter, which is working except it counts lines that  
wrap as new lines making the count not accurate. Any ideas of how to  
fix this? Thank you.
