xargs exit status

The xargs command is not returning the correct exit status if a sub-process has
a non-zero exit status.
Example...

$ false
echo $?
1
$ echo hello | xargs false
echo $?
0
$

This contradicts the man page...

"EXIT STATUS
       xargs exits with the following status:
       0 if it succeeds
       123 if any invocation of the command exited with status 1-125
       124 if the command exited with status 255
       125 if the command is killed by a signal
       126 if the command cannot be run
       127 if the command is not found
       1 if some other error occurred."

Thus, the false example above should have given an exit status of 123.

Seems to be behaving correctly in current Dapper:

mizar:[~] echo hello | xargs false
zsh: done echo hello |
zsh: exit 123 xargs false
mizar:[~] echo $?
123

Please reopen if you find otherwise.
