+
+# This widget uses the completion system to double-quote the current word
+# if it is not already quoted, then attempts to complete normally.  If the
+# normal completion fails, the quotes are removed again.
+#
+# To use it:
+#   autoload -U quote-and-complete-word
+#   zle -N quote-and-complete-word
+#   bindkey '\t' quote-and-complete-word
+#
+# BUG: The "undo" mechanism is confused by multiple calls to completion
+# widgets from the same normal widget.
+
+# Note: It's important that this function's name ends in "complete-word".
+# The _oldlist completer does nothing unless the widget has that suffix.
