+# Complete words from the history

+# by Adam Spiers, with help gratefully received from
+# Sven Wischnowsky and Bart Schaefer
+#
+# Available styles:
+#
+#   list --  avoid to display lists of available matches
+#   stop --  stop before looping at beginning and end of matches
+#   sort --  sort matches lexically (default is to sort by age)
+#   remove-all-dups --
+#            remove /all/ duplicate matches rather than just consecutives
+#   range -- range of history words to complete
