Applies to the specification of the return value of a function.

The wording of warnings about unsatisfiable guards that used
'not' was incorrect (the 'not' was not mentioned and it appeared
as "Guard test is_atom(atom()) can never succeed").
|
|
Apart from the obvious bug in the negative evaluation of an 'and'
guard, Dialyzer handled dont_know cases rather single-mindedly
towards the positive branch. This patch allows for negative results
as well and does some clever guesses to narrow them down. It was
constructed similarly to the handling of the 'not' guard.
