npm-scripts that start with pre or post can run, but cannot run their pre/post commands

[hail2u]

I'm opening this issue because:

• npm is crashing.
• npm is producing an incorrect install.
• npm is doing something I don't understand.
• Other (see below for feature requests):

What's going wrong?

If I created npm-script named preview, npm run preview works fine. However, prepreview or postpreview script does not run with this command. The same occurred on present, poster, or a word that starts with pre or post.

How can the CLI team reproduce the problem?

In package.json:

{
  "scripts": {
    "prepreview": "echo pre script for preview",
    "preview": "echo preview",
    "postpreview": "echo post script for preview"
  }
}

and then

$ npm run preview

Result:

> @ preview ~/Desktop/test
> echo preview

preview

Expected result:

> @ prepreview ~/Desktop/test
> echo pre script for preview

pre script for preview

> @ preview ~/Desktop/test
> echo preview

preview

> @ postpreview ~/Desktop/test
> echo post script for preview

post script for preview
