The documentation of the function '''monomial_all_divisors''' states that
the function
"Return a list of all monomials that divide" the input.
The polynomial 1 is considered as a monomial dividing any monomial but is
not returned by '''monomial_all_divisors''' (see code below for an
example).

{{{
x,v=var('x,y')

print "1 divides m:", R.monomial_divides (one, m)
print "List of monomial divisors of m:", R.monomial_all_divisors(m)
print "Is 1 in it:", one in R.monomial_all_divisors(m)
