The by_name/ entries are symlinks into by_key/, but their inodes are
left with i_size 0, so 'ls -l' and lstat() report a size of 0 for them.
Set i_size to the length of the link target, as other filesystems do.
Replacing the leading spaces with "../" afterwards does not change the
length of the target, so it is safe to take it right away.
