nimble run does not pass command-line arguments to executable
When specifying command-line arguments after the `nimble run` command-line, I expect those to be passed to the execute program but they are not:

```
INS mildred@faile:disputatio.nim/a$ nimble init a

In the above session, the command-line arguments is empty `@[]` while I expected the `--help` flag to be passed.
