Run platform pre/post commands if default or combination is specified

[psylum]

I'm not sure if this would be reasonable as a feature, since it does add some implied logic to what will run, but given the following package.json as an example:

{
    "name": "run-script-os-test",
    "version": "1.0.0",
    "description": "shows desired use of pre/post handling.",
    "scripts": {
        "preascript:win32": "echo 1 - win32 prep",
        "preascript:nix": "echo 1 - linux prep",
        "ascript": "run-script-os",
        "ascript:default": "echo 2 - platform neutral command",
        "postascript:win32": "echo 3 - win32 cleanup",
        "postascript:nix": "echo 3 - linux cleanup"
    },
    "dependencies": {
        "run-script-os": "^1.1.6"
    }
}

If you do the following, here's the actual results:

$ npm install
# ..installation output elided..
$ npm run ascript

> [email protected] ascript /root
> run-script-os


> [email protected] ascript:default /root
> echo 2 - platform neutral command

2 - platform neutral command

I'd sort of expected the following:

$ npm run ascript

> [email protected] ascript /root
> run-script-os


> [email protected] preascript:nix /root
> echo 1 - linux prep

1 - linux prep

> [email protected] ascript:default /root
> echo 2 - platform neutral command

2 - platform neutral command

> [email protected] postascript:nix /root
> echo 3 - linux cleanup

3 - linux cleanup

Based on the readme, i had hoped that doing this might be a workaround, but it similarly does not trigger pre/post:

"ascript:nix:win32": "echo 2 - platform neutral command",

Would this type of behavior be useful, even if behind a flag passed to run-script-os that could be added to the main 'ascript' command? This would make the package.json far less verbose, but still allow for "handling" all the os specific things as necessary, since in many cases the actual command invocation doesn't change between platforms. I know that you can make this work with the current implementation by adding:

"ascript:win32": "echo 2 - platform neutral command",
"ascript:nix": "echo 2 - platform neutral command",

But as i've stated, it'd be nice to remove the additional verbosity if it could identify the platform or combo that will run and appropriately run the pre/post scripts associated.
