[gedit-list] Enter tab to overwrite selection?

[Doug McNutt <douglist macnauchtan com>]

gedit 3.4.1 on ubuntu 12_04
---> Copy and paste from a table on a web page - Firefox - I see:

Confirmation Number
    6H99-B42C-XZXH Print
Payment Selection
    Current Balance

---> Select from the space after the n terminating "Confirmation" through the space before the 6. Type a tab.

---> Result is:

Confirmation Number
    6H99-B42C-XZXH Print
Payment Selection
    Current Balance

--->Note the position of the tabs,  What I expected is:

Confirmation	6H99-B42C-XZXH Print
Payment Selection
    Current Balance

---> Is there a reason?

I do use the add-in that tabs a whole block of code at once but I select whole lines when I do that.
I also have stuff from 2008 thru 2011 where gedit has always done what I expected.
