#compdef -K _history-complete-older complete-word \e/ _history-complete-newer complete-word \e,
#
# Complete words from the history
#
# by Adam Spiers, with help gratefully received from
# Sven Wischnowsky and Bart Schaefer
#
# Available styles:
#
# list -- display lists of available matches
# stop -- prevent looping at beginning and end of matches during
# menu-completion
# 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
