Oh, it's probably a bug.  Here's what's happening there:

    a \\
    (:include A:)(:nl:)(:include B:)(:nl:)(:include C:)(:nl:)
    b

The \\ becomes a line break and join, thus

    a  <br />(:include A:)(:nl:)(:include B:)(:nl:)(:include C:)(:nl:)
    b

after the includes we're left with

    a  <br />(:nl:)(:nl:)(:nl:)
    b

and the first (:nl:) turns into a newline because there's no newline
at that point.  Thus we finally end up with

    a  <br />

    b

and the blank line gives us the paragraph.

So, I should probably have the rule treat repeating sequences of
(:nl:) directives as a single one, which would seem to solve the above
problem.
