My most recent post was a query about inserting a range of page entries into
the header of each page.  After digging through the TeX book, I have come up
with half of the solution.

If I \mark each entry, I can then use \firstmark and \botmark to insert them
into the headers.  This works fine for single column documents.  However, in
double column documents, each column is treated as a separate page, so the
real \firstmark is lost by the time the header is built:

HEADER: range = XN+1 - XN+M

          COLUMN 1                                      COLUMN 2

          \mark{X1}                                     \mark{XN+1}
              .                                            .
              .                                            .
              .                                            .
          \mark{XN}                                     \mark{XN+M}

Thus, as you can see, the header will contain the range XN+1 - XN+M, where
what I really want is X1 - XN+M.

I'm using latex, and so in experimenting with the \output routine, I get
some strange results, since latex does some redefining.  Does anyone know
how I can adapt latex's output routine to do this properly?
