Remove all zero-value Imbalance-XXX splits?

[Jeff Kletsky]

Many transactions seem to end up with zero-value Imbalance-USD splits 
that make it hard to ensure that all transactions have valid splits as 
we go along.

Is there a way (short of munging the XML or database directly) of 
removing such "meaningless" splits?

You can't easily open the Imbalance-USD register view and delete them 
from there.

Thanks!
