Hmmm...  Interesting way of starting the action of selecting something *before*
you have typed the text that you want to select.  I do not posses this amount of
foresight.  :)

(In your particular example, I would have typed:    '10'<Tab>=> ^K^U^U^U, and
then gone back to type the stuff after the =>'s, and then changed the second
10 to 20, and third 10 to 30.)

Yes: nano-2.9.2 added a simple rule to the keyboard routine: when the mark is 
on,
<Tab> calls the indent function instead of inserting a Tab character.

We could change the rule so that <Tab> only means 'indent' when the cursor is
on a different line than the mark.  This would preserve the intention of the
function (to be able to indent a group of lines as a whole), without interfering
with your foresight selecting -- well: unless you type multiple lines, including
Tabs, while the mark is on.  Is there any chance you would do the latter?  If
yes, then you would simply have to delete lines 661 and 662 from src/winio.c.

But if you make only short foresight selections, then the attached patch
should fix the problem.
