I thought of another thing we should change: it's better to perform
the test as "off > (dp - dest)" than the way you formulated it.
"dp - dest" is certainly computable, since it's the number of bytes
we've written to the output buffer so far. But "dp - off" could,
with bad luck and a buffer near the start of memory, wrap around
to look like it's after "dest".
Pushed with that change and a little fiddling with the comment.
Thanks for the report!
