Comment(by cremona):

 Note that #5347 (merged in 4.1.2.alpha2) fixes the easy cases I listed
 above.  We still have
 {{{
 sage: Zmod(5)(1).divides(Zmod(2)(1))
 True
 }}}
 but this looks fine to me:
 {{{

 sage: Zmod(2).zero_ideal() == Zmod(2).zero_ideal()
 True
 sage: Zmod(2).zero_ideal() == Zmod(2).unit_ideal()
 False
 }}}

 Hence the patches here need to be rebased and simplified to cater for the
 first one.
