Manual: Incorrect explanation of /\B/

Currently we have this text (in 3.7):

Matches the empty string that occurs between two word-constituent
characters. For example, /\Brat\B/ matches ‘crate’, but it does not
match ‘dirty
rat’. ‘\B’ is essentially the opposite of ‘\y’.

It should read:

Matches when not at a word boundary, i.e., within a word or whenever both
of the adjoining characters are not a word character.  For example,
/\Brat\B/ matches ‘crate’, but it does not match ‘dirty rat’, or  /\B/ matches
4 places in ‘///’.  ‘\B’ is essentially the opposite of ‘\y’.
