Shouldn't `holo-files apply` exit with a non-zero code on error?

[LukeShu]

In holo-files/impl.TargetFile.Apply() if there is an error, it is logged to os.Stderr, then discarded.

	if err != nil {
		fmt.Fprintf(os.Stderr, "!! %s\n", err.Error())
	}

This seems to me to contradict holo-plugin-interface(7), which says

The apply operation

...

If an error occurred during provisioning, the plugin shall exit with non-zero exit code.

So if holo-files/impl.TargetFile.Apply() encounters an error, shouldn't avoid having a zero exit code? Or is this a bug in the documentation?

Note that if holo-files is modified to have a non-zero exit code in this case, then the test suite would need adjusted, as holo would start spitting out !! exit status 1 lines in response; and the test suite won't be expecting them.

Sounds plausible, but I distantly remember that there was a reason for doing it this way. I will check during my next meditation. :)
