* Hardlink entries don't own data blocks; their data is represented by the
* target file. If a hardlink pathname is selected while its target file is
* excluded by a path filter, keep the target selected as well so check/fix
* can process the data backing the selected hardlink.
* With the missing filter, a present target must remain excluded because
* fix -m promises to leave existing files untouched. It can be used directly
* to recreate the missing hardlink without processing its data.
