Description

When creating recursively directories with mkdir -p, the watcher only reports the first directory.

Steps to Reproduce

1. Install the CLI from #180
2. Run watcher /tmp
3. Execute mkdir -p /tmp/foo/bar/baz

Expected behavior:

The watcher says that directories foo, foo/bar and foo/bar/baz have been created:

created directory: /tmp/foo
created directory: /tmp/foo/bar
created directory: /tmp/foo/bar/baz

Actual behavior:

The watcher only says that the directory foo has been created:

created directory: /tmp/foo

Reproduces how often:

Always.

Versions

I've used the master branch of @atom/watcher.

Additional Information

As far as I know, inotify is not recursive, and it's @atom/watcher code that creates sub-watchers for directories inside the watched directory. When inotify sends the event for foo, the directories foo/bar and foo/bar/baz have already been created, so even if the watcher is able to find these directories to tell inotify to watch them, it fails to also send an event for them.
