traces: always print the reduced grammar and fix it

Browse Source 
* src/gram.c (grammar_dump): Print the effective number first instead
of last.  And fix it (remove the incorrect "+1").
Use t/f for Booleans.
* src/reduce.c: When asked, always print the reduced grammar, even if
there was nothing useless.
* tests/sets.at (Reduced Grammar): Check that.
