No, this is the text:

      Return a new matrix formed by extracting extract the lower (`tril')
      or upper (`triu') triangular part of the matrix A, and setting all
      other elements to zero.  The second argument is optional, and
      specifies how many diagonals above or below the main diagonal
      should also be set to zero.

The word "extract" on the first line should be deleted.  This would be 
correct:

      Return a new matrix formed by extracting the lower (`tril')
      or upper (`triu') triangular part of the matrix A, and setting all
      other elements to zero.  The second argument is optional, and
      specifies how many diagonals above or below the main diagonal
      should also be set to zero.

I am cc'ing this to the Bug list.
