Description:
        The builtin read command does not work like e.g. dash or zsh w.r.t.
        the null character '\0', however I'm not sure it can be
        considered as a bug.
        If a line containing the '\0' is read into a variable, the content
        of this variable does not contain the part after the '\0' character.

Repeat-By:
        echo -e 'a\0b' | (read f; echo $f)

        The output is 'a', and '\0b' is stripped.
