This will probably work on most Unix implementations, but it is not
guaranteed.  An implementation is allowed to ignore trailing
whitespace when reading in the file.  (This is to facilitate coding in
environments with fixed length records, where the system always pads
your line of code with blanks to make it the fixed length.)
