Better handling of initial spaces when commenting / uncommenting.

What steps will reproduce the problem?
1. Select lines with // comments preceded by initial whitespace.
2. Select comment / uncomment.

What is the expected output? What do you see instead?
An extra level of commenting is added to the lines.  Instead, I would expect 
the comments to be 
removed - if all of the lines are commented.  

That is:
  //  int x = 0;
  //  x = x + 1;

should become:
  int x = 0;
  x = x + 1;

Although I would still expect:
  // create a variable x
  int x = 0;
  x = x + 1;

to become:
//  // create a variable x
//  int x = 0;
//  x = x + 1;
