Output not shown in certain cases

[majgis]

I've found two different cases where the output of faucet is mysteriously missing:

1. webstorm npm integration
   • executing a task through the npm tool window shows other output to stdout but not from faucet
2. nodemon, example shown below

package.json:

  "scripts": {
    "test": "faucet",
    "test-auto": "nodemon --exec 'npm test'",
    "test-auto2": "fsmonitor -s npm test"
  }

cli:

$ npm test

> test-config@1.0.0 test /Users/user/projects/test-config
> faucet

✓ getGlobalConfig returns default when process.env is not set
# tests 2
# pass  2
✓ ok

$ npm run test-auto

> test-config@1.0.0 test-auto /Users/user/projects/test-config
> nodemon --exec 'npm test'

[nodemon] 1.9.1
[nodemon] to restart at any time, enter `rs`
[nodemon] watching: *.*
[nodemon] starting `npm test`

> test-config@1.0.0 test /Users/user/projects/test-config
> faucet

^C

$ npm run test-auto2

> test-config@1.0.0 test-auto2 /Users/user/projects/test-config
> fsmonitor -s npm test


Monitoring:  ~/projects/test-config
    filter:  **/
    action:  npm test

npm test

> test-config@1.0.0 test /Users/user/projects/test-config
> faucet

✓ getGlobalConfig returns default when process.env is not set
# tests 2
# pass  2
✓ ok

......

I initially created an issue with nodemon, but it was suggested that the issue could be with how faucet is detecting the stdout stream.
