* src/scan-gram.l: Add %option nounput, since we no longer use unput.
(unexpected_eof): Renamed from unexpected_end_of_file, for brevity.
Do not insert the expected token via unput, as this runs afoul

All uses changed to BEGIN the parent state,
since we no longer insert the expected token via unput.
* tests/regression.at (Invalid inputs): Remove cascaded diagnostic
that is no longer emitted after the above change.
* src/conflicts.c (set_conflicts): Resolve all conflicts, not just * src/conflicts.c (set_conflicts): Resolve all conflicts, not just
