command-line emacs tops out at 16384?

[Sanford Selznick]

I've created a file "/tmp/test" that contains 20000 characters.  If I 
execute the following command on it from a console only the first 16384 
characters are input.

Why is this?

This is supposed to execute c-style wrapping on /tmp/test, and works 
great for file lengths < 16384.

emacs -batch -eval '(find-file "/tmp/test")' -eval '(c-mode)' -eval 
'(indent-region (point-min) (point-max) nil)' -eval '(save-buffer)' 
-eval '(kill-buffer (current-buffer))'

Thank you,
  Sanford
