In most cases where this function is used, suppressing only the standard output is more appropriate. Culling diagnostic output hides error messages and makes debugging more difficult and confusing. `$DRY_RUN_NULL`, which the `--silence` flag replaced, was used both for suppressing standard output on its own, and for doing so along with diagnostic output; however, when the `run` function was added this distinction was lost, and both outputs would be discarded. This reintroduces the needed functionality, and changes usages of `--silence` to `--quiet` where previously only standard output was suppressed, or where this should have probably been the case anyway.
