I suspect the problem would be with Pandoc's definition of 'line' and 
'file'.  Pandoc like many unix tools only really appears to read files 
as a convenience to the user - it's really reading streams of lines. 
You can pass it multiple files, and it just treats them all as one big 
stream of lines.

So I suspect Pandoc has no real idea of line numbers or files when 
working on things - it just knows that it saw an error in the current 
line being read.

(As a further complication: If you're reading markdown or similar, what 
is a 'line'?  Do you mean anything that ends with a newline, or do you 
mean any contiguous block of text that could be written as one line? 
That is: Does wrapping the text alter the number of lines in the file?)
