Fixes #2358.
"Uninteresting" tags are exempted -- this includes "attribution", "created_by", "source", "odbl", and "tiger:*". The values of such tags will continue to be joined with semicolons.
The rule also takes into account tag values that will automatically be reversed when the ways are joined. For example, if you have a
oneway: yes
way from a to b, and aoneway: -1
way from c to b, joining is permitted, and will produce aoneway: yes
way going a to b to c.
