[TYPO3-mvc] Viewhelper arguments in shorthands

[Sebastian Fischer]

Hello Sebastian,

well atleast its clearified here now. I for myself would still prefere 
the possibility to have both, but i know that then all would get 
complicated. So for now i could live with this. It's only somehow unusual.

Thanks explaining it.

Greetings
Sebastian

PS: Still feels like soliloquy (and yeah i had to search for that word) 
writing with you :D
