We do want that trailing \n, unless we move it to commands_string.

Also, I think using error_report here would be confusing -- this is a standalone
test program with as little QEMU-specific knowledge as possible (QemuThreads
are used for portability); using error_report here is confusing (this is not
an error).

? I don't know what this is, I don't seem to have this binary in my
checked out tree.

Same as above: this removes the necessary trailing \n.

ditto -- I'd rather keep fprintf(stderr) here, it's less confusing.

Thanks,
