I've now added this to Emacs 28. I added it as a fallback (when the
external programme doesn't exist), because that seemed least likely to
break something, but we could consider reversing the code (since it's
likely to be faster to use the internal function).
This also reminded me that I wanted to add a function that does the
"reverse" of `insert-buffer-substring', which I don't think we have. That
is, to allow saying
(let ((buf (current-buffer)))
(with-temp-buffer
(create-lots-of-data)
(insert-into-buffer buf (point-min) (point-max))))
in an efficient way. When dealing with temporary buffers, you have to
contort yourself to use `insert-buffer-substring' in the other
direction, and
(insert
(with-temp-buffer
...
(buffer-string)))
is pretty inefficient.
