That's not really good enough. That is, your program is to going to
tell you "I can't do that" when you ask "give me the next line".
Fine, you're not crashing, but you really want that line!

There ought to be a Get_Line which returns an Unbounded_String (did
I get that right?), so that space for it comes from the heap instead
of the stack. And yes, I know it's a security issue because someone
can feed the program unbounded input and have it chew up large chunks
of RAM, but sometimes you really do need unbounded lengths on your
input lines. I've often posted the example of a .newsrc file I had
where a line of interest was well over 100,000 characters long.
