Excessive requirement for a title

[Robert Matthews]

In the Mongo code there is a line that gets an object's title from the 
adapter using

        field.titleString()
but it is flagged as deprecated and the suggested new use (from line 58 
in ObjectAdapter) would require me to say

        field.titleString(field)

which seems a bit silly to me. Has someone got a bit deprecation happy :-)?
