Autocompletion eats words

[i.am@…]

If you start typing a name in front of a word and tab complete it, the word you started typing before is eaten up by the completion.

Scenario: replying to someone, FooUser, you've typed out your sentence:

"hello, I am saying something_" (_ = current position)

You remember to prefix the message with their name, so you go to the front:

"_hello, I am saying something"

You type their name, and complete it with <Tab>, and you end up with this:

"FooUser, I am saying something"

FooUser replaced "hello"; this would happen for any other word as well (doesn't have to be at the start).
