- IMHO, the -N option (+new-files) would be more useful if it would
- affect only files in the new directory. New files would get inserted
- in the diff, deleted files would not.
-
- This is especially useful when using shadowed source trees where it
- doesn't make any sence to include unchanged files in the diff (which
- occurred to me when I got some 20 MB diffs where there really were
- only a few changes).
-
- The following simple fixes implement this change.

- to affect neither label, just the first file's label, or both labels.
- A file's default label is its name, a tab, and its modification date.
-
- ! -N in directory comparison, if a file is found in only one directory,
- ! treat it as present but empty in the other directory.
-
- -p equivalent to -c -F'^[_a-zA-Z]'. This is useful for C code
- because it shows which function each change is in.
