Unfortunately, (make-string 50 ?*) is the single character '*', I was
shooting for something that was a repetition of two characters (*SPC) so
that my section divider looked like:
/* * * * * * * * * * * * * * * * * * * * */
I would begin and end the function with (insert 47).
I tried (insert (make-string 5 "* ")) and variations thereof, i.e. with
and without quotes and ASCII numbers.
