The project file already includes an entry for adding the capability
of reading files that contain columns of numbers without any header
information, so it will probably eventually be implemented (it may
happen faster if someone else actually does the work, though :-).

I believe that it is a bug that you can't avoid the error message with
fscanf().  I'll see about fixing that (and other similar problems with
the C-style I/O functions) for the next release.
