dialyzer: Extend the map implementation's handling of ?unit

2017-11-22T14:07:46+00:00

The Maps implementation handles ?unit in more cases.

Exactly when t_is_none_or_unit() is to be called is not clear to me.
The added cases are about a map type being ?unit, but the key or the
value of an association can also be ?unit, but that is not always
checked.

dialyzer: Use string:find() instead of string:str()

dialyzer: Display error messages without call stack

2017-11-10T15:36:02+00:00

As of commit 12b379 many of the reasons displayed after
"Analysis failed with error:"
erroneously include a call stack. The bug is now corrected.

The bug was pointed out in
http://erlang.org/pipermail/erlang-questions/2017-October/093838.html.
