[SVN] r7278 (C, Objective-C) for loop changes

This change didn't show up for me until now (strange, because other  
recent changes did).
It diminishes the value of the for loop snippet considerably, IMO:

- A size_t makes sense for looping over byte arrays in primarily-stdio  
code, but for nothing else. Can we resnippetize the variable type?
- Any use of ++ is bad practice, it makes the variable value undefined  
anywhere else in the current expression. This is not a fun bug to  
track down when you get bitten by it.
- Use of prefix ++ here looks weird.

Thanks,
Chris
