No, it is guaranteed to have a not-null value by the time it is
referenced. This function is called only if archive name contains
a ':' (see rmtcreat). This means that case ':' in rtapelib.c:418
will always be executed and will assign a non-null value to
remote_file, unless it has already been assigned one.
