I "solved" the problem I had with the particular doc that prompted me to
post this question by Saving As rtf and reopening and re-saving as Word.

The original file's problem may have been that it contained (at some
point) automatically generated references (using a program like Endnote).
Or the file might have been European, or Mac, or Mac European, who knows?

Yes, that happens sometimes. I see it mostly in files that are imported from
other formats, especially with text files that don't use one consistent sort
of line end (CrLf versus Cr versus Lf...).
Saving in any Word format (doc or rtf or docx or xml) and re-opening does
usually fix it.

Another way to fix it would be to replace ^13 with ^p and, if necessary, ^10
with ^p -- since the problem is that Word didn't recognize some of those as
"real" paragraph marks on import.
