Bash Version: 2.05
Patch Level: 8
Release Status: release

Description:
        The bash builtin "read" command does not seem to handle piped input.
I expect piped input to be handled like terminal input.  The Posix shell
version in HP-UX does do this.

Repeat-By:
        echo "12 34 56" | read A B C
        echo $C $B $A
        expected return "56 34 12"
        actually returns nothing
