I put that in some buffer (say *scratch* -- but loading the file from
disk works too), execute the definition by putting point at the end
and doing C-x C-e. Then the function is defined.
After that, I go to the buffer I want to test for the longest line,
do M-x eval-expression <RET> (goto-longest-line) to call the function.
Point ends up (so one hopes :) at the buffer's longest line.
As I said, there are bugs in there, so beware :-)
Cheers
