 	This option specifies a function to be used for Insert mode completion
 	with CTRL-X CTRL-U. |i_CTRL-X_CTRL-U|
-
-	The function will be invoked with two arguments.  First the function
-	is called to find the start of the text to be completed.  Secondly the
-	function is called to actually find the matches.
-
-	On the first invocation the arguments are:
-	   a:findstart  1
-	   a:base	empty
-
-	The function must return the column of where the completion starts.
-	It must be a number between zero and the cursor column "col('.')".
-	This involves looking at the characters just before the cursor and
-	including those characters that could be part of the completed item.
-	The text between this column and the cursor column will be replaced
-	with the matches.  Return -1 if no completion can be done.
-
-	On the second invocation the arguments are:
-	   a:findstart  0
-	   a:base	the text with which matches should match, what was
-	   		located in the first call (can be empty)
-
-	The function must return a List with the matching words.  These
-	matches usually include the "a:base" text.  When there are no matches
-	return an empty List.
-
-	When searching for matches takes some time call |complete_add()| to
-	add each match to the total list.  These matches should then not
-	appear in the returned list!  Call |complete_check()| now and then to
-	allow the user to press a key while still searching for matches.  Stop
-	searching when it returns non-zero.
-
-	The function may move the cursor, it is restored afterwards.
-	This option cannot be set from a |modeline| or in the |sandbox|, for
-	security reasons.
