Emit modification event for the creation of a non-empty file

[Ash Wilson]

Some platforms emit both a created and modified event for the creation of a non-empty file:

await fs.writeFile('file.txt', {}, 'contents\n')

{ action: "created", kind: "file", path: "/root/file.txt" }
{ action: "modified", kind: "file", path: "/root/file.txt" }

This is the technically correct behavior, because from the perspective of the filesystem, fs.writeFile performs two distinct operations: open("/root/file.txt") and write(fd, "contents\n").

• Add a test case to ensure that this is happening consistently across platforms.
  • MacOS
  • Windows
  • Linux
• Change watcher-stress to expect the immediate modification.
