What is elisp idiom for continue until end of buffer

What is elisp idiom for continue until end of buffer

[acomber]

I created this elisp function

(defun fmt-tbl () 
  "format Word tables for wiki"
  (interactive)
  (goto-char (point-min))
  (insert "{||-")
 (while (search-forward "\t")
    (delete-backward-char 1)
    (insert "|")
  )
  (goto-char (point-min))
  (while (search-forward "\n")
    (insert "|-")
  )
  (goto-char (point-max))
  (insert "|}")
)

Which fails at  (while (search-forward "\n").  I also tried 
 (while (end-of-line)
   (insert "|-")
 )

But that also didn't work.

How can I repeatedly goto end of line on each line until EOF?

`search-forward' takes an optional *third* argument, NOERROR. First
(required) argument is the string to search for, second is a buffer
position to limit the search to (set to nil for whole buffer), and the
third should be set to 't' to keep the function from exploding when no
further matches are found.

Not once I have I used this function without setting NOERROR to 't'.
