I simply missed that, and didn't adjust it with the offset like i did
I also just noticed that the line numbers displayed in the stack window
are also off by one. They would be hard to adjust with the approach I
tried, because you need the source of a function before you know whether
there's a newline in the beginning, and we don't load the sources for a
function until you display it. And the line numbers in any error
messages you get on the console also won't match what we display.
This becomes particularly visible if you enable line numbering in the
left margin. I tried to be clever and merely hide the first blank line
in the text box, so that the control's numbering would seem to start
from 2, but I couldn't get wxStyledTextCtrl::HideLines() to hide the
first line. If you pass it 0, it does nothing, and 1 means the 2nd line.
I think we have to give up on hiding the initial newline. A blank line
in the beginning is a bit ugly, but it's better to be consistent.
Attached is a patch to do that.
