Existing lines are not emitted until the file is updated

[lbovet]

The existing lines are emitted only when the file changes. This is not like tail(1) which dumps directly the current content.

Is there a way to achieve this or is there a missing flag?

Currently, I worked around with:

    FileObservable.tailer()
            .file(file)
            .tailText()
            .startWith(Observable.defer(() -> {
                try {
                    return Observable.from(Files.readAllLines(Paths.get(file)));
                } catch (IOException e) {
                    return Observable.error(e);
                }
            })

(Note: I defer in order to be sure that I do not miss lines)

Well, I found the bug, this is a minor thing. It happens only when using the builder. I'll submit a PR asap.

Thank you very much for this @lbovet! I'll review soon.

Any news on this? Seems like a pretty small change to review with a potentially-big impact.
