Remember last message's tab completion for next tab completion
When I'm sending multiple messages to the same person in a MUC, I would like the tab-completion to automatically complete the nickname, even when the person does not answer in between.
Example, in a MUC with bob, bill and belle (in the order of activity):
I type `b hi` and end up sending 'belle: hi'.
Then I type `b` and I would like to see 'belle: ', however I end up with 'bob: '.
