Recursive copies in dired abort on first error

[Sven Joachim]

Recursive copies in dired fail rather ungracefully: if an error occurs
for one file the whole operation is aborted, leaving the remaining
files unprocessed.  See the following example: A dired buffer looks
like this:

,----
|   /tmp/foo:
|   total used in directory 15 available 265502
|   drwxr-xr-x  2 root root  1024 Aug 27 21:41 .
|   drwxrwxrwt 13 root root 11264 Aug 27 21:39 ..
|   -rw-r--r--  1 root root     4 Aug 27 21:39 bar
|   -rw-------  1 root root     5 Aug 27 21:40 topsecret
|   -rw-r--r--  1 root root     5 Aug 27 21:41 whynot_copied
`----

Now, in Dired I switched to /tmp and tried to copy foo recursively to
my home directory (I have `dired-recursive-copies' set to 'top) which
failed with the error

Copy `/tmp/foo' to `/home/sven/foo' failed:
(file-error Opening input file keine Berechtigung /tmp/foo/topsecret)

(For the non-Germans: `keine Berechtigung' means `permission denied'.)

After that, the directory for ~/foo looked as follows:

,----
|   /home/sven/foo:
|   total used in directory 12 available 1797044
|   drwxr-xr-x  2 sven sven 4096 Aug 27 21:42 .
|   drwxr-xr-x 47 sven sven 4096 Aug 27 21:42 ..
|   -rw-r--r--  1 sven sven    4 Aug 27 21:39 bar
`----

, confirming that the copy operation was aborted after the failure on
the `topsecret' file.
