#172 [pack symbol] accepts non-symbols

[Hans-Christoph Steiner]

If [pack symbol ...] receives a message with just a selector,
then it treats it as if it was a symbol. I.e. this packs a symbol:

[test( <--this works
|
| [test( <-- this throws an error
| |
[pack symbol symbol]

Tested on Mac OS X: 0.40-2 and 0.39.3-extended-rc5.

So does [symbol] -- left inlet takes an anything, right inlet (obviously) only takes a symbol. Is that a bug, too?
