Jakob Borg a9f0659f2f lib/fs: Handle deduplicated files on NTFS (fixes #1845)
These files always have the symlink bit set, because they are reparse
points. Nonetheless they are not symlinks, and Lstat reports a size for
them. We use this fact to disambiguate, and hope fervently that nothing
else matches this description so it comes back to bite us...
