Problems with "|0.5rt" in lout 3.39

[James, Voyle E USA CTR (US)]

Hello lout users,

I have found a difference in the results of "|0.5rt" that may be based on 
either descender characters or special characters.
Attached is a sample input file, test.lout, and the result postscript file, 
test.ps.

What I want, is the changemark, a plus sign, at the left margin, and the text 
centered in the column.
One way works on text without the comma and the other works with the comma.

If this is a "feature" I can call the correct macro if I know what characters 
to check for, descender or any special.

Thank you,

Ed
