osis2mod seems to fail on long entries

I'm in the process of converting the module "Luther" to OSIS and
expanding it (the current version only covers Galatians). Luther wrote
a "Church Postil", which was equal parts Sermon/Commentary for all of
the Gospel texts in the 1-year lectionary. Some of these are LONG.

I've found a bug that seems to have something to do with entry length. As an
example, I've attached a test module. This module has text in 3 verses
only:

Mark 1:1 - This has one whole sermon ... note that this is only an
example, some are much longer
Mark 1:2 - This has the first half of the sermon; no differences in
markup at all, paragraphs 1-39
Mark 1:3 - this has the second half of the sermon, paragraphs 40-80

When you check out the results, you can see that each half displays
correctly. The combined verse, Mark 1:1, cuts off in the middle of
verse 16.

This seems to be happening in quite a number of the sermons. The OSIS
file validates, and the markup doesn't seem strange at all. I can't
figure it out.

I built the module with:
[bjdasc@ascpc5] osis2mod mod/ test-longentries.osis -z -b 3 -v KJV
You are running osis2mod: $Rev: 2435 $

Thanks,
Brian
