[BusyBox] ps does not quote meta chars

latest cvs, libc5.

If I use in inittab
...respawn... /bin/getty -I "\033[H\033[J" 38400 tty2
I can do "$ ps"

If I use
...respawn... /bin/getty -I "<ESC>[H<ESC>[J" 38400 tty2
(<ESC> is real ESC typed in vi as CTRL+V->ESC)
"$ps " causes the screen to be cleared (it interprets the excape sequences)
when the output reaches the getty line.

Another "ps" automatically converts <ESC> to \033 in its output.

In my case I can just use \033 in inittab, but maybe this can cause
unexpected problems in other conditions (ie one puts up a process with weird
chars in it and ps interprets them doing something bad).
