Hi,
I found that at least since Squeak-5707, syntax error messages like:
'right parenthesis expected ->' don't appear on the right position when
what you are evaluating is not on the first line.

For example if you paste the following 4 lines on a Workspace and
evaluate only the last one:

  Line 1
  Line 2
  Line 3
  (OrderedCollection with: 1

instead of:

  Line 1
  Line 2
  Line 3
  (OrderedCollection with: 1 right parenthesis expected ->

You get: 

Line 1
Line 2
Line 3
(Orde right parenthesis expected ->redCollection with: 1
