diff output.c @ 185:16b4451e34b8
Add the ability to output line numbers, sort of.
It is enabled with the intentionally undocumented -p option (similar
to -P but reversed sense) and it might be vaguely useful but only
prints the line number when the file changes and may not get the line
numbers right.
