Problem with readline

[Fairlight]

Only Alan Mazuti would say something like:

You're casting "ln" as 80 long.  I suspect you're hitting a line longer
than 80.  It is documented that it should use the length of the field but
it sounds like a bounds checking bug was introduced.

Two potential workarounds depending on your goal:

1) Specify a 3rd argument, "80", for readline if you really only want the
first 80 characters.

2) Use "ln" uncast, and specify "32767" as the third argument to readline.
That will give you the full line to the NL, and resize the field.

This assumes the bug is only of medium severity.  These might not work if
it's really hosed badly.
