declare output of process substitution after redirection.

[admn ombres]

i'm not sure this must be considered as a bug, but using bash 4.2.45
(end it seems to be the same in the devel branch) the output of :

f1 () { y >& >(z) ; }
f2 () { y &> >(z) ; }
declare -f f1 f2
f1 ()
{
    x &>>(y)
}
f2 ()
{
    x &>>(y)
}

# look like a bug

source <(declare -f f1 f2)
-bash: /dev/fd/63: line 3: syntax error near unexpected token `('
-bash: /dev/fd/63: line 3: `    x &>>(y)'

hope this help.
