mm macro footnote/end-of-page problem

[Bill Brelsford]

                           Groff Bug Report

GROFF VERSION:  1.18.1

MACHINE:  IBM-compatible Pentium IV

OS:  Linux 2.6.21.5 (Debian Etch or Sid)

COMPILER:  none (using Debian package)

INPUT FILES:  foo.tr (attached)

COMMAND LINE:  groff -mm foo.tr    # using groff version of mm

DESCRIPTION OF INCORRECT BEHAVIOUR:
        The footnote reference occurs with exactly enough space
        remaining on the page for the footnote.  The end-of-page
        trap is apparently clobbered; text continues over the page
        boundary and the footnote appears on the next page.  As
        expected, if the footnote-reference line is moved one unit
        higher or lower, it works properly with the footnote
        appearing on the same or next page, respectively.

SUGGESTED FIX [optional]:

foo.tr
