It may be clearer to `drop_front` (or `substr`, it's the same thing but my
functional bias prefers drop) from `remaining` as we go, instead of referring
to `text` all the time.
So you print up to where the match is, drop_front however much that was, print
the match, drop_front the size of the match, etc, etc.
That way the algorithm is all centered on `remaining` and we aren't referring
back to `text` the whole time.
And it can be summed up as "while there is remaining text keep printing it".
