Ok. I totally dig the *idea* here - I mean, this issue has been ongoing 
for a long time now. But I'd like to see a few comments as to whether we 
need a technological mechanism here to enforce the obvious. To me, it 
just seems totally obvious (any legal comment?) that early C string 
termination is undermining the intent of the MODULE_LICENSE tag.

The m-i-t patch seems ok and also cleans up the existing logic.

Jon.

P.S. Someone's fooling around with mailman on that box, I'll get the 
mailing list sorted out between now and the weekend or somesuch.
