Example:
```lang=console
$ arc patch --force D104
Created and checked out branch arcpatch-D104.
Downloading binary data for 'fail.png'...
Checking patch Tests/ClientTests/fail.png...
error: Tests/ClientTests/fail.png: already exists in working directory
Patch Failed!
Usage Exception: Unable to apply patch!
```
Seems to me that `--force` should be a little more forceful in this case, no?
