Re: describe-text-properties highlighting and mouseover face is broken

[Richard M. Stallman]

    To avoid more confusion, I want to remind that the initial complaint
    was about link buttons in the Help buffer created by 
describe-text-properties
    which uses buttons from wid-edit.el without mouse-face on them.

I think it would be clearer to have mouse-face on them.  In fact, I am
not convinced it is ever a good idea for any kind of link or button in
Emacs to use a mouse-pointer change instead of mouse-face.  It is
inconsistent.  Inconsistency can be acceptable when there are benefits,
but I see no benefits.
