Regex help (targetting very long HTML comments)

[Kris Deugau]

Can anyone point out what bit of stupidity I'm committing in trying to 
use this:

rawbody OVERSIZE_COMMENT        m|<!--(?!-->).{32000,}|s
to match messages that are mostly very very long HTML comment(s)?

Testing the same regex against the whole raw message outside of SA seems 
to fire just fine.
