Reading in a file certainly counts as a change in the buffer, so a q command in that circumstance should be rejected. I suppose a case could be made that if the read-in file is empty, the modified flag should not be set, but I think that would be more confusing.
I think the case for not setting the modified flag when reading an empty file is indeed strong because, well, the buffer has not been modified, and a subsequent undo won't be able to reset the flag.
