There does not seem to be.

Looking at the code, at least with my eyes, truncation seems difficult
and will probably end up as a hack.
I've attached a patch that copies some of the functionality of the '%w'
handling, and should be applied to the newest source on savannah. It
seems to produce the correct result, although someone more familiar with
the code should check it for any unwanted consequences.
