If there is a leading space on the line this won't find it.

This won't either.

Of course, any well-formatted script won't have spaces before a  
handler definition, but that doesn't stop the script from compiling.  
Checking the first word of each line is (I believe) certain, and is  
still reasonably fast (takes less than twice as long as the filter  
command in informal testing).

Unfortunately for anyone attempting this task, this is a perfectly  
valid script:

/* this is a comment
as is this */on mouseUp
   answer "yes"
end mouseUp

I don't know of a good way around that, so I have ignored it thus  
far ;-)
