I chanced to notice while thumbing through lcov reports that we had exactly no coverage of BETWEEN SYMMETRIC, nor of current_time(N) and localtime(N). Improve that. parse_expr.c still has a pretty awful coverage number, but a large part of that is due to lack of coverage of the operator_precedence_warning logic. I have zero desire to write tests for that; I think ripping it out would be more sensible at this point.
