Yes, I am aware of that. If I want i to output I use echo  
KEW_short_excerpt();. But that's not the thing. The thing is that the  
filter gets applied if I use echo inside the function, or if I use  
echo apply_filters('_theme_short_excerpt', KEW_short_excerpt()); in  
the theme with the filter targeting _theme_short_excerpt.

But if I use return apply_filters('_short_excerpt',$text); in the  
function and echo KEW_short_excerpt(); in the theme, the filter does  
not get applied.
