The case

The archive has a directory, then a file a. The pax header of the directory has a path of 120 ds, followed by a slash, and its header has the first 100 bytes of that path.

The pax path overrides the name field of the directory, and an extended header applies to the next file only: the tree is the directory and a.

N43-pax-long-dir: must accept, and extract its tree

A directory with a long name in a pax `path`, then a file.

The archive has a directory, then a file `a`. The pax header of the directory has a `path` of 120
`d`s, followed by a slash, and its header has the first 100 bytes of that path.

The pax `path` overrides the name field of the directory, and an extended header
applies to the next file only: the tree is the directory and `a`.

Seen in: tarballs with long names from Python's `tarfile` and GNU tar in pax format.
See also: N03, a long name of a file in a pax `path`.
