Thank you both. I have addressed this and some related (and unrelated
things I noticed along the way) with the attached patch:

On this website...

https://www.gnu.org/software/sed/manual/sed.html#Invoking-sed

In 2.1, the very first example in the documentation states that...

	sed 's/hello/world/' input.txt > output.txt

... replaces ALL occurences of 'hello' to 'world in input.txt.

But the g flag is missing. The provided command only replaces the FIRST 
occurence.
