The use-case is, AFAIU, the 'find' program: when it recurses through
deep directory hierarchies, it uses openat() to avoid producing too
long file names. Right?

The Austin Group may want to introduce posix_spawn_file_actions_addfchdir
OR posix_spawn_file_actions_addopenat and posix_spawn_file_actions_addchdirat.
AFAICS, you wouldn't need both in the standard. So, I would wait until the
Austin Group has debated this alternative.
