Our gEdit application has a line/column feature, but the line numbers only
count to the bottom of the text widget, so when you move down it stays at
the same number. If you would be willing to try and get the line count
function working, I (and Evan) would be very pleased (As we cannot see how
it is done either, the header doesn;t give much away, and the source file
doesn't either)
