line number display to StyledEdit

[chico]

1. open the StyledEdit.
2. hold on key 's' to write multi-lines.
3. you can the right line number in StyledEdit. Then you drag the window smaller. You won't see the line number change.

Expected: the line number will change with the window resizing, if the line number is surely changed. And I don't think it's a bug, but we can do better.

look at the cursor and the line number

StyledEdit does have a line number display (yet), but if it did, it "should" be showing a 4, since it should be counting the number of lines in the file, not the line number that the cursor ends up on when you make the window smaller. Closing as invalid.
