PATCH: documentation for new _history_complete_word

[Adam Spiers <adam@xxxxxxxxxxxxxxxxxxxxxxx>]

This patch should only be applied at the same time as my rewrite of
_history_complete_word.  The rewrite didn't make it into pws-6; maybe
because there are still (very slight) problems with duplicates
removal?  Any ideas on solutions to this problem, or will we have to
wait for Sven to get back?
