bug#10489: 24.0.92; dired-do-copy may create infinite directory hierarchy

Gnus/5.13 (Gnus v5.13) Emacs/24.0.94 (gnu/linux)
I'm afraid there are still problems. I encountered these two:
1. Creating symlinks to parent directories doesn't work anymore.
E.g. if you have a directory "~/test/dir1/", open a dired for "~", go to
"test/", hit S, enter "~/test/dir1/" and hit RET. You get the error
dired-create-files: Cannot copy `/home/micha/test' into its subdirectory
But I only wanted a symlink... This worked in Emacs 23.
2. Symlinks to parent directories (still) lead to ininite loops when
copying containing dir.
To use the above example: just create this symlink from outside Emacs,
so you get e.g. this:
total used in directory 8,0K available 94267456
drwxr-xr-x 2 micha users 4,0K Mär 22 02:32 .
drwxr-xr-x 3 micha users 4,0K Mär 22 02:33 ..
lrwxrwxrwx 1 micha users 22 Mär 22 02:32 test -> /home/micha/test
Now dired "~", and copy "~/test" to "~/test2". You get a hierarchy
again (the command terminates without error, btw). And all these
are real directories, and _not_ symlinks!
I also wonder why dired doesn't copy the symlink itself, but copies the
target instead? This seems to be the case also in other examples. If I
copy a directory containing any symlinks with dired, copying always
copies the targets of the symlinks.
