This is ready to go. Changes:

• All 3rd party imports in the Git LFS code and the vendored libs should have a "github.com/github/git-lfs/vendor/nut/" prefix.
• Somehow the "github.com/kr/pty" package was never vendored. It is now.
• The various scripts are now much simpler. Should work with vanilla go commands, even on Windows.
• Forked "github.com/bmizerany/assert" to fix an import statement in an example script. This gets around this issue.
• There are references to "github.com/ogier/pflag". I think we need to clean up some references in some of spf13's packages upstream.

Why nut? Mostly because it worked out of the box. Godep didn't work quite right, and required a hack to get around an issue. We've also had great interactions with Nut's author, @jingweno in past Go projects. He mentioned an intent to support the suggested Go import conventions with a community specified vendor file format.

Looks fine to me. I never had the issue you encountered with godep (didn't have any platform-specific imports) and found it worked fine with updates over time - I see nut update isn't implemented yet - but it's all much the same. Main thing is the rewriting of the imports so it'll build out of the box which is a big plus.

Looks good, a couple notes:

Right now nut doesn't have an option to just rewrite imports (owenthereal/nut#8). This means manually typing the full vendored import path, and tools like goimports will no longer be able to help with that. If nut had this, for example, that could be part of the editor's formatting command (or script/fmt), run after goimports. This isn't a deal breaker, just something we might trip over.

Updating support would be nice, but working around that is pretty much what we had to do with gpm, so not a big deal (actually seems a little easier, I always had problems with gpm and .git dirs).

Running nut install in a freshly checked out version of this branch I get this every time:

This is code in a commented block, I'm thinking it got rewritten on accident and nut is just putting it back to normal, though I would think that no tool should be rewriting imports in comments. I think it should be safe to put that back as the normal import so we don't have to fix it every time we run nut.

@rubyist: Ah, that might've been rewritten by me originally, and nut is just fixing it. I didn't realize it was in a giant comment block.

I went back and looked at the commits and realized that's probably what happened 👍

Thanks for using nut! I'll prioritize owenthereal/nut#8 higher since quite a few people ask for it.

@technoweenie How do you fix the assert issue? I saw your fork but I'm not sure how to integrate!
