It should not matter if flags given before command or after

[brandon-leapyear]

This happened in a wrapper script, when I'm setting default flags to pass to stack; e.g.

#!/bin/bash
STACK_ARGS=(
    --test --no-run-tests
    --bench --no-run-benchmarks
)
exec stack "${STACK_ARGS[@]}" "$@"

Steps to reproduce

1. stack --test --no-run-tests build
2. stack build --test --no-run-tests

Expected

Either both should build tests and not run them or neither should work (since stack doesn't take those flags on its own)

Actual

The first built and ran tests. The second built but didn't run tests.

In other words, stack --test build and stack --test --no-run-tests build do the same thing.
