This is very weird.  If at least the NUL byte was between the transposed
regions, but in the middle of one of the two?

FWIW, I took a look at `transpose-regions` in case there was something
fishy in it.  I saw a problem with handling of text-properties in an
unrelated corner case (fixed on `master`), but nothing that would
explain the above.  🙁

Same here for now,
