yes, I prefer the filter name, because if I want to dig into a problem I'll 
likely use filters. I think for most dissectors short and filter name just 
differ in capitalization and my brain typically wouldn't notice any difference, 
so it may not make any big difference.

Side note: it may be worthwhile to add a recommendation to the check-api program 
that short name and filter name should case insensitive compare equal.
