…eError read_po parsed the plural index of a `msgstr[N]` line with `int(idxarg[:-1])`, which leaked a bare `ValueError: invalid literal for int()` to the caller when N was not an integer (e.g. `msgstr[\x0c]`). Route a non-integer index through the parser's existing `_invalid_pofile` handling, so it raises a `PoFileError` when `abort_invalid=True` and otherwise warns and skips the line, consistent with other malformed input.
