Well, something is going awry; I have no idea what. Two of us have tried Andrew's variation to no avail; it still hangs. I can't figure out why it is hanging at a 3-cap acronym, after which the very next one is the same, with different letters. There is no parenthesis in between the two, which are even on the same page.

So, it seems that the two-pass solution, unless I have misunderstood it, is stymied in this case, because neither Paul's nor Andrew's will continue past a fairly early page, each hanging at a different point.

Let me say that we have done this by inserting Andrew's line under Paul's and commenting it out, and then tried commenting out Paul's and enabling Andrew's.

There must be something I am not getting about running these (surprise, surprise).

I'm sorry I can't send the text.
