I did a quick bit of strace-ing, and it seems that sed isn't closing the
input and output files before doing the rename. Unsurprisingly, this fails
with "Access is denied.".

But sed is trying to close the files. It gets as far as
lib/utils.c:ck_fclose(stream), but then it does something complicated with a
linked list, and ends up never calling do_ck_fclose(), which would actually
call fclose().

Right, I've got no more time now, so hopefully someone else will take my
analysis, and finish tracking down this bug.

Max.
