[Greasemonkey] Basic JavaScript questions

[chris feldmann]

Sorry, accidentally sent. Anyway, I wanted to note that simply cut and 
pasted, your script works just fine for me. The log looks like this:

/inner: removing node [object Text] all.length: 21
/inner: removing node [object Text] all.length: 20
/inner: removing node [object Text] all.length: 19
/inner: removing node [object Text] all.length: 18


And all the H3's are gone. Possibly the include parameter is not being set 
correctly on install (I seem to have to do it manually as a rule)?
