This was not really accurate. Being `read-only' is a Windows phenomenon on open files (even files open for reading). In 2.0.1 and 2.1.1 the file was open whilst it was parsed and so `read-only' during that time. In 2.0.1 it was then closed, but in 2.1.1 it was (potentially) opened several times to find an encoding, parsed and left open until source() terminated. In 2.2.0 it will be closed once it has been parsed.
Changing a file after it has been parsed will have no effect, so there is no reason to prevent it (beyond that was the simplest way to implement choosing a suitable encoding).
