When I run across such a text file,
I use hex-mode to see what is going on.
In every case I have seen, the problem
is due to a malformed end-of-line pattern.

Emacs recognizes and hides standard end-of-line patterns
if they are use consistently.

MAC-like  (CR)
DOS-like  (CR+LF)
Unix-like (LF)

Corey's file probably has the end-of-line pattern
CR+CR+LF where the first CR is printed ^M
while the CR+LF is interpreted as a DOS end-of-line and hidden.

In this case I would do

(buffer-to-unix)

to fix up the end-of-lines
and then a query-replace of the ^M characters to nothing.
