CUA rectangle mode may use the old behaviour to place cursor midway
through a tab character - I cannot judge from your example if that
is still working with the trunk code, and I don't have time to check
one out (I got lost in the Bazaar)...

But you can easily try it out.
Just enter:

M-x cua-mode RET
a C-q C-i b
C-a C-RET C-f C-f C-f ..

cursor should move successively from a through the tab until it reaches b
