"Localisation" tends to mean something quite different around here.
I'd suggest renaming the function to something like ReportSyntaxErrorPosition.
Would it read better to add "..." at the front and/or back of the query
extract, when you have actually truncated text at that end?
The "on line N" bit seems just noise to me.
