Elliotte,
It seems this bug was introduced in xmlstarlet.
mikhail@greybox /cygdrive/c/msys/1.0/home/mikhail/XMLSTARLET/libxml2-2.6.5
$ echo "<xml/>" | xml c14n --with-comments -
<xml></xml>
[new line here]
mikhail@greybox /cygdrive/c/msys/1.0/home/mikhail/XMLSTARLET/libxml2-2.6.5
$ echo "<xml/>" | ./testC14N.exe --with-comments -
<xml></xml>
mikhail@greybox /cygdrive/c/msys/1.0/home/mikhail/XMLSTARLET/libxml2-2.6.5
I will fix it in CVS and I will let you know.

Subject: [xml] Possible bug in canonicalization

> Canonical XML draft placed a #xA after each PI outside of the document
> element as well as a #xA after the end tag of the document element. The
> method in this specification performs the same function except for
> omitting the final #xA after the last PI (or comment or end tag of the
> document element). This technique ensures that PI (and comment) children
> of the root are separated from markup by a line feed even if root node
> or the document element are omitted from the output node-set.
