Two NSFileManager questions

[Enrico Sersale]

1) NSFileManager, in -_copyPath:::, when encounters a directory, tries to 
create a new destination directory with the same attributes of the source; if 
the directory is created but the attributes can't be set it skips the source 
contents, even if _proceedAccordingToHandler::::: returns YES.
I'm wondering if this is the right behaviour or if it should be considered a 
bug.
It seems to me a bit restrictive; if I'm a user and I want to make a copy in my 
home directory of an external directory for which I've read access, this should 
be allowed; in this case NSFileManager should try to change only the 
permissions but not owner and group.

2) I can't find a way to remove broken symlinks; -removeFileAtPath:: doesn't 
work in this case.
