bug#31135: 26.1; documentation of left-word and right-word are unclear

[Robert Pluim]

The documentation strings for left-word and right-word both say:

  Value is normally t.
  If an edge of the buffer or a field boundary is reached, point is left there
  there and the function returns nil.  Field boundaries are not noticed


1. Which value is normally t?
2. 'there' is repeated in the second sentence.
