Subject: logger: fix --size use for stdin
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The stdin version counts log header into the message size, but
for example when it reads message from argv[] it counts only message
itself.
$ logger --stderr --size 3 "abcd"
<13>Oct 21 18:48:29 kzak: abc
$ echo "abcd" | logger --stderr --size 3
logger: cannot allocate 18446744073709551597 bytes: Cannot allocate memory
