[TxMt] C bundle: Functions with multi-line argument lists

[John Kooker]

Ha, sorry to imply that 2.0 needed to be the "achieve world peace"  
release. I just thought it was pretty common practice to have multi- 
line function prototypes, which would make this bug a pretty big  
deal. But I guess you're right - it's features vs. performance, so  
there will always be trade-offs. Thanks for the explanation!
