And I am happy with the following patch as well (it should be applied
with the patch I posted in the previous mail).

This patch adds guessing the default target directory for dired-diff.
If there is no mark in the current dired buffer, then it takes the target
directory name from the next window using `dired-dwim-target-directory'.

Another feature is that if no files are marked in the current dired
buffer (i.e. dired operates on the file under point) then when reading
the target file name it uses the current file name as the initial
input string for C, R and some other dired commands.  This is
especially useful when renaming files: the prompt places the name of
the current file as the basis for file name editing.
