Sigh.  This is the wrong way to do this.  It is much easier to implement a new
subclass of the PlainDocument class, such that it overrides the
"insertString()" and "remove()" methods.  In those methods, you keep track of
the current number of characters in the "model" so you can restrict the total
input length.  This will also deal properly with pasting into the field, which
your code doesn't deal with at all.
