Try placing the caret at column 2 and use shift arrow down a few times, 
you'll get (X shows the selection):

   XXXXXXXX
XXXXXXXXXX
XXXXXXXXXX
XX

Pressing option once turns this into:

   |
   |
   |
   |

This does IMHO make perfect sense, especially if you couple it with 
column-movement, or if you start with the caret at the last line and 
instead use shift arrow up.

Making the exception only when caret is at column 0 still would give a 
problem with column movement, e.g. if you have:

|foo
  bar
  fud

or

  foo
  bar
|fud

In first version you can use option-shift down + option and in the 
second you can use option-shift up + option both to get to:

|foo
|bar
|fud
