the trick is: what does it mean when there are fewer values in a row?
There is no way to universally define that.
Anyway, I'd just punt on using a standard ascii file reader, in the
time it took to write this question, you'd be halfway to writing a
custom file parser -- it's really easy in Python, at least if you
don't need absolutely top performance (which loadtext and genfromtext
doen't give you anyway)
