Placement of dots

[Joseph N. Srednicki]

Please see the following example. 

Note: There have been some recent issues of the mail programs lopping thing
off such a final brace when pasting examples. I re-pasted the following
example and recompiled it before sending this message. So, I am hoping that
it comes through without anything missing.

In the middle voice in the second measure of the example below, the two g
notes in the middle voice move the dots to the right of the g. 

Instead, I would like to move the dots next to the notes to which they apply
instead of the position following the intervening g notes.

I looked at Snippet http://lsr.di.unimi.it/LSR/Item?id=674.

According to this snippet, the command \override
Staff.NoteCollision.prefer-dotted-right = ##t is supposed to move the dots
to the position to the immediate right of the notes to which they apply; no
notes are supposed to intervene between a note and the dot to which it
applies. 

Therefore, in my example, the notes should appear to the left of the g notes
in the second measure.

However, I tried placing the \override
Staff.NoteCollision.prefer-dotted-right = ##t in a variety of locations, but
to no avail.

For example, I tried using a \context {\Staff ... statement in a layout
block. I also tried putting the statement in the global variable. In yet
another try, I placed the \override before a particular dotted 

Can someone please tell me how what I am misunderstanding or doing
correctly?

Ideally, I would like to make this change globally for the entire score.

Thanks in advance to anyone who can help with a suggestion or correction.
