I've got a really big (40mb) XML file.
There are some Base64 binary blobs in the xml, some of them are around 16-30KB.
By default, Slick wraps these around 4000 characters -- so some of these "lines" appear as several lines in Slick.
For a given blob that shows up as about 5 lines in Slick, it is on line 70.
In the status-bar, Slick shows line 70 no matter which of these lines the cursor is in.
It shows 71 when the cursor moves past this.
When I use GUI-Goto, to go to line 71, it moves the cursor to the 2nd line of the blob -- the virtual line 71.
Basically, the status bar appears to show the real line numbers, while gui-goto shows and interprets the line numbers as virtual (taking into account the splitting that slick has done).
