Line number for a binary change (without hunks) #122

debdiff generates diff files such as the one in the unit test seen in:

cpina@7510966

I'd like to know which line of the diff the line: Binary files Binary files /t/p1/a.png and /t/p2/a.png differ is.

Since it doesn't have hunks I don't think that this is currently possible.

In PatchSet._parse there is unused_diff_line_no which likely contains it. I think that perhaps this could be added to PatchedFile and then the caller would have easy access.

Actually in other cases I get the line number of the first hunk of the file and substract 3 to get what would be the line number of the file.

Have this been discussed? I might propose an implementation if could be merged at that level (PatchedFile) but I haven't checked if this would require bigger changes everywhere.
