[Message part 1 (text/plain, inline)]

Hello (sorry for my bad English),

I am using coreutils 8.15 and have noted that `yes' ignores the
environment variable `POSIXLY_CORRECT'.

So the command `env POSIXLY_CORRECT yes --help' does print the help
instead of printing `--help' until killed.

In addition `yes' cannot be killed with CTRL+C (SIGINT) or CTRL+Z
(SIGTSTP) if you call it with another program using the `&' operator of
sh. This causes that `yes & <insert_random_program_name_here>' can only
be stopped with CTRL+D which causes a logoff. `yes & yes'
however can only stopped if killed from another terminal ...

Is this wanted or are these bugs?

Thank you for your acknowledgement.
