script for quickly finding large functions

[Joris Huizer]

Hello,

I made this script to find large functions; I think it may be usefull to 
add at the janitorial page where the note on large functions was placed;

It assumes no things are between functions, so it gives some incorrect 
matches; also, it accidentilly reads some if() and switch() statements, 
but in some (most) cases those are actually in large functions if they 
show up high.

I hope this is usefull, it did find some interesting large functions 
like HRESULT WINAPI IDirectMusicContainerImpl_IPersistStream_Load 
(dlls/dmloader/container.c) which has like 7 levels of nested switch 
statements

regards,

Joris
