[SVN] C bundle doesn't recognise multi-line function defintions

It absolutely needs to match the closing paren, otherwise you do get  
false positives. I'm not certain that it has to match the closing  
paren with lookahead, though. (Feel free to disabuse me of that notion.)

If we could get the last clause of the regex to always match the open- 
curly-bracket ({|\n\s*{)
instead of ({|\n), the problem would go away. I don't remember  
whether I've already tried that or not, nor do I remember whether  
multiline regexps work in this context. Have to find some time for TM  
hacking...
