This is known behavior for some older implementations of sed, among other things. The behavior of many utilities is undefined on lines that don't end in a newline. If you have it, you might try gsed.

readproctitle
readproctitle(8) System Manager's Manual readproctitle(8)
NAME
readproctitle - maintains an automatically rotated log in memory for inspection by ps(1).
readproctitle is available in daemontools 0.75 and above.
SYNOPSIS
readproctitle L D
DESCRIPTION
L consists of any number of arguments. D is one argument consisting of at least five dots.
readproctitle reads data into the end of D, shifting D to the left to make room. This means that the most recent data is visible to
process-listing tools such as ps(1). readproctitle always leaves three dots at the left of D.
For example, if
readproctitle io errors: ....................
reads the data
fatal error xyz
warning abc
then its command-line arguments change to
readproctitle io errors: ... xyz!warning abc!
with a newline character in place of each !. Process-listing tools typically show the newline character as ? or
.
readproctitle exits when it reaches the end of input.
Beware that most implementations of ps(1) have small argument-length limits. These limits apply to the total length of readproctitle L D.
I have not seen a system with a limit below 512 bytes.
