    [me]: Squawk if columnation change w/ pending ftn.
    
    * tmac/e.tmac (2c, 1c): Throw diagnostic if changing columnation with a
      footnote pending.  This isn't necessarily an error per se, but it many
      cases it will flag an undesirable page layout due to the limited
      flexibility of me(7)'s footnote support at present.  See
      <https://savannah.gnu.org/bugs/?63176>.
