Agreed.  I think that giving an error is preferable to silently 
accepting the code, since there are probably compilers other than 
GFortran out there that cut the lines short and then give cryptic error 
messages.  And thus we're not really doing programmers any favors by not 
letting them know about the problem.

Probably the best option would be to read in the whole line without 
truncating it, but (by default) give a warning about the line being 
overlength.

(I'd be glad to put that on my to-do list and get to it in a month or 
so, unless someone else wants to work on it.)
