some NSFileManager bugs

[Enrico Sersale]

(due of my bad English I'll use a pratical example)

take a directory that contains some subdirectories, some plain files and a
symlink to one of the directories like this:

[root@img1 sviluppo]# ll GSPdf
total 168

1) copy the directory to an other location, for example "GSPdf_copy"
(I'm not using GWorkspace for this, only a simple program that calls
NSFileManager's -copyPath:toPath:handler: in main).

well, only the directories will be copied and, moreover, "obj" is not
anymore a symbolic link but a directory and contains the contents of
"./shared_debug_obj/ix86/linux-gnu/gnu-gnu-gnu".

2) try now to create an empty directory and copy *the contents* of the
first dir to the second one.

in this case, all the files are copied but "obj" is not anymore a symbolic
link;

3) now, using -removeFileAtPath:handler: try to remove the entire
directory "GSPdf" (the first one, that with the symbolic link).

the directory will not be removed and, if you cd into it, you will see
that all the files have been removed but not "obj".

run again your little program and, this time, the directory will be
deleted.
