Please use the existing coding style when proposing changes and never re-format any code.

  for I := 0 to Variables.Count - 1 do begin
    WriteRegistry(Variables.Names[I], Variables.ValueFromIndex[I]);
  end;

is changed to:

  for I := 0 to Variables.Count - 1 do
  begin
    WriteRegistry( Variables.Names[ I],
                   Variables.ValueFromIndex[ I],
                   True);
  end;

Note the blank line, the begin and the line break between parameters, which are totally unrelated to the intended code change.
This is how it should look instead:

  for I := 0 to Variables.Count - 1 do begin
    WriteRegistry(Variables.Names[I], Variables.ValueFromIndex[I], True);
  end;

The current changes lead to an inconsistent style and the real code changes are obfuscated by the style change.

While I accept projects having a different style than I prefer, I still take the right to enforce my style on my projects.
