The documentation of AUTO_NAME_DIRS
<https://zsh.sourceforge.io/Doc/Release/Options.html#index-AUTO_005fNAME_005fDIRS>
states
that any parameter set to an absolute path becomes a named directory but
currently setting any value turns the parameter into a named directory.

- Restrict named directories to scalar parameters set to a path
<https://github.com/paltherr/zsh/compare/restrict-nameddirs-to-scalars...paltherr:zsh:restrict-nameddirs-to-paths>
(depends on workers/54759 <http://zsh.org/workers/54759>)
