Are you sure this works with quoted arguments?

[lsnow99]

No but I didn't think the original code did either, but I see now why you have it passing the entire string as the second argument. However I don't think that works unless you make the first argument a shell like sh or bash. The reason I have this PR is because the current code does not work on a shebang like #!deno run --allow-read=./store.json. It throws error: Found argument 'run --allow-read=./store.json' which wasn't expected, or isn't valid in this context. Do I dare suggest using an external package? ;)

This is a valid point. I went down a bit of a rabbit hole looking at this when I wrote it the way I did, and if I was to include an external package, it would be that one – the code is simple and clear.

I was being a little obsessive about accuracy at the cost of practicality, and in the meantime, I think your PR is a solid compromise. Might just be worth amending it with a comment linking to this discussion and removing the outdated comment (since it no longer behaves as described by the comment).

Fuck it. If we're gonna fix this, might as well fix it right. It's worth adding the external package.

Once you make that change, I'll merge it. Thanks!
