Copying files out of symlink directory
When copying (Ctr-C) a file that is in a symlink directory (a->b, a/foo.txt), if the symlink changes(a->c) or gets deleted before pasting (Ctr-V), the file that was copied (foo.txt) can not be found because the location from which it was copied has a different content now (a/foo.txt doesn't exist because a -> c and c/foo.txt doesn't exist). I hope this is understandable.
In my opinion the logical behavior should be that copying files (that are not symlinks themselves) should "copy" the path to the target file(b/foo.txt instead of a/foo.txt) and should not be affected by symlink directories changing. At least I can't think of a situation where the current implementation would be preferred.
