When entering a name with variable expansion, the "invalid character in

variable name" error was never cleared.

- inst.c (validate_pad_name): call status_begin_reporting before expanding the
  string, to clear any previous error
- expr.c (expand): if the last character in the name is a dollar sign, print
  "incomplete variable name" instead of "invalid character [...]"
