Subject: bug#72604: 29.2; 29.2; when using customize to set ispell-program-name to ispell, ispell-library-diectory is set correctly, but not for aspell

Hi

Steps.

    - emacs -Q

    - describe-variable ispell-program-name: /usr/bin/aspell

    - describe-variable ispell-library-directory: nil

    - (setq ispell-program-name "/usr/bin/ispell")

    - describe-variable ispell-library-directory: nil

    - customize-option ispell-program-name /usr/bin/aspell

    - describe-variable ispell-library-directory: nil

    - customize-option ispell-program-name /usr/bin/ispell

    - describe-variable ispell-library-directory: /usr/lib/ispell

Conclusion, customize-option sets ispell-library-diectory correctly if I
set ispell-program-name to ispell /usr/bin/ispell
but not if I set it to ispell /usr/bin/aspell

This is not really a bug, but a lack of a feature, no?

Regards
