I believe it is fully expanded by default in `customize-option' but not
in `customize-group'.

A special command to expand would be useful, I think.

But users might still want an easy way to get the variable into the help
buffer.  For example, they might be using helpful.el that displays all
kinds of additional information in that buffer, or they might just
prefer having a separate buffer to display the documentation.  I'm in
the latter camp; expanding documentation on the customize screen itself
makes it harder to get an overview of all available options, so I often
would rather put the full length docstring in a separate buffer.
