 To "fill" a hole marked by one of the aforementioned commands, either
 use ~C-c C-m~ as described above or type ~C-w~ (~M-x kill-region~) to kill
 the region and remove the placeholder variable, and then insert Prolog
 code as usual.  Yanking a hole with ~C-y~ (~yank~) after you kill it
 removes the special hole property and inserts it as a plain variable.
-This is particularly useful if you want to keep the variable name that
-Sweep chose for the hole--to do that simply press ~C-w C-y~ with the
-hole marked.

 As an alternative to manually killing the region with ~C-w~, with
 ~delete-selection-mode~ enabled the placeholder is automatically deleted
