option to do non-gui diff and get the comparison output
Sometimes, we want to programmatically compare two folders and return the status if the files are same or different or missing. In that case, if meld can do such a comparison and return 0, 1 or 2 implying same, modified, missing, it would be nice. If it can return the status for all files separately, then it would be more helpful. Example command with no graphics -
>>meld -ng file1 file2
0>> meld -ng dir1 dir2
file1 0
file2 1
file3 1
file4 2
