Generalizes #3556 to not suppressing errors in tactic steps either when the parse error is in a later step, as otherwise changes to the end of a proof would affect (correctness or effectiveness of) incrementality of preceding steps. Fixes #4623, in combination with #4643

Incomplete syntax should not suppress errors in previous definitions as that would prevent reuse.
