Move point N words to the right (to the left if N is negative).
Depending on the bidirectional context, this may move either forward
or backward in the buffer. This is in contrast with M-f
and M-b, which see.
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
if `inhibit-field-text-motion' is non-nil.
