report: put the dot after %empty in items

Browse Source 
When printing items, it is clearer to put the dot after %emtpy rather
than before:

     0 $accept: . unit "end of file"
     1 unit: . assignments exp
-    2 assignments: . %empty
+    2 assignments: %empty .
     3            | . assignments assignment

Also, use the Unicode characters if they are supported.

* src/gram.c (item_print): Put the dot after %emtpy.
* tests/conflicts.at, tests/reduce.at, tests/report.at: Adjust.
