Comment #8 on issue 2376 by address@hidden: Automatic footnotes on \null  
markups causes unexpected results

Patchy the autobot says: LGTM.  But I don't like all that performance hit  
just because footnotes are missing a copy-stencil call.  Would you be ok  
with constant stencils if one had a way to mark them readonly and/or  
copy-on-write?  Which of the two would you prefer?
