Cleaning up sqlplus cut and pastes in vim

Classical problem, you write a short piece of SQL in sqlplus, you then want to cut and paste it to vim edit it. But then you get the really annoying line numbers in front of each line.
Sure you can use save myquery in sqlplus and open the file myquery.sql in vim, but perhaps you want to run vim on another machine, perhaps you run gvim.
So ok, time to get rid of the line numbers.

Here's what we got in sqlplus:

SQL> list
  1  select
  2  e.ename,
  3  d.dname
  4  from
  5  dept d,
  6  emp e
  7  where
  8  d.deptno=e.deptno
  9* order by e.ename
SQL>

Lets cut n paste those numbered lines to a vim session.
We now need to delete the first 4 characters of each line. Easy.
Switch to visual mode, jump to the end of the file, step two rows right, hit delete char.
Or in vim command terms (in normal mode (esc-esc)).

ctrl-v G l l x

Breakdown:
ctrl-v to get in to visual mode
G to jump to the end of the file
l to move the cursor right
x to delete the selected area

Visual mode is quite powerful, you can use almost the same commands to comment out code.
Place the cursor in the first line you want to comment out, hit ctrl-v to do a visual mark, use j to move the cursor down to the last line you want to comment out, hit I to get insert, type two hyphens and hit escape. Done.
In vim command terms:

ctrl-v j j j I -- esc
