This should be doable.

What should be the perferred format?

Something like

filename:line\tOutput goes here

would be possible, or without the file name

line\tOutput goes here

The latter would have the advantage that it would be fairly easy to
line up the declarations from modules, which probably should not
have line number annotations.

And what would be preferred - having a new option to control line
numbering, or doing it unconditionally?
