I tried to append together the previous and current lines, like this:

        I am a heading\n**************\n

Then something like this:

       :loop
       s/^\(.\)\(.*\)\n\(.\)\(.*\)\n/\2\n\4\n/

t is a test; if the last s/// was successful, it branches to the indicated label

labels are introduced by :
