bug#64354: 29.0.91; (emacs) `Registers'

[Drew Adams]

The node says this in the beginning:

 A register can store a position, a piece of text, a rectangle, a
 number, a window configuration, or a file name, but only one thing at
 any given time.  Whatever you store in a register remains there until
 you store something else in that register.  To see what register R
 contains, use 'M-x view-register':

But the subnodes also talk about holding a frame-configuration in a
register.  Should the top-level node be updated similarly?
