My mistake, it was the ExPex package (described here recently) that seems
not to automatically break lines. At least that's what I understand its
documentation to be saying, e.g. the example on pg 26-27 of
   http://www.math.neu.edu/ling/tex/expex-doc.pdf
which appears to have the line breaks hard-coded.  I hope someone (John
Frampton?) will correct me if I'm mis-interpreting this.
