I use only one-window frames (pop-up-frames non-nil). Each buffer is displayed in its own separate frame. What is the significance of the frame parameter `buffer-list'? The doc says only this: `buffer-list' A list of buffers that have been selected in this frame, ordered most-recently-selected first. Even if a particular frame has only ever displayed a single buffer, this parameter can apparently have various values. For example, here are two different values of `buffer-list' for the frame *Help*, which has never displayed any buffer other than buffer *Help*: (buffer-list #) (buffer-list # # #) What is going on here? Is this a bug? If this is the intended behavior, then just what is that behavior? What determines (changes) the value of `buffer-list'? I can find no doc on this. Motive: I'm trying to test for equality (with `equal') between frame configurations, and the same frame with all other parameters equal is showing up with different values for `buffer-list'. I don't want to have to create and pass a different equality predicate (that would ignore `buffer-list'); I want to be able to use `equal', if I can. Thanks, Drew
