Could you please recompile with the fprint part of the code I sent 
before? Then start with "emacs -Q". For me a continues output from the 
frpintf statements starts immediately, something like the below. It 
stops if I enter some text and continues if I go to the beginning of the 
buffer and then press left arrow again.

cont=0, start.string_pos=-1, 1, end=-1, 67
cont=0, start.string_pos=-1, 1, end=-1, 67
cont=0, start.string_pos=-1, 1, end=-1, 1
cont=0, start.string_pos=-1, 1, end=-1, 67
cont=0, start.string_pos=-1, 1, end=-1, 1
cont=0, start.string_pos=-1, 1, end=-1, 67
cont=0, start.string_pos=-1, 1, end=-1, 67
cont=0, start.string_pos=-1, 1, end=-1, 67
cont=0, start.string_pos=-1, 1, end=-1, 67
cont=0, start.string_pos=-1, 1, end=-1, 67
cont=0, start.string_pos=-1, 1, end=-1, 20
cont=0, start.string_pos=-1, 1, end=-1, 1
cont=0, start.string_pos=-1, 1, end=-1, 20
cont=0, start.string_pos=-1, 1, end=-1, 20
cont=0, start.string_pos=-1, 1, end=-1, 20
cont=0, start.string_pos=-1, 1, end=-1, 20
