nl_func_var_def_blk has unwanted effect

[RobertoBagnara]

$ uncrustify -v
Uncrustify_d-4dbe0768

$ cat p.cfg
nl_func_var_def_blk = 1

$ cat p.c
void g () {
  h();
  int x;
  return;
  {
    h();
    int x;
    return;
  }
}

$ uncrustify -c p.cfg p.c
Output suffix: .uncrustify
do_source_file(1505): Parsing: p.c as language C

$ cat p.c.uncrustify
void g () {
    h();
    int x;

    return;
    {
        h();
        int x;
        return;
    }
}

The first occurrence of int x; is a variable definitions not at the top of a function body, hence is should not be followed by a blank line.
