(eq custom-buffer-style 'links)
and go ahead indenting the documentation if such condition holds.

Then, we don't need `this-command', so that the doc will be indented
also in non-interactive calls.

    customize-apropos: Separate package name from its description
    
    * lisp/cus-edit.el (custom-group-value-create):
    Always insert documentation indented from its package name (Bug#31466).
