A copyright (?) issue with a message helper function

[Marcin Borkowski]

Hi list,

I'm writing myself a function to ask me whether I really want to send
a message without an attachment if it contains a string like "I
attach".  I'd like to submit it as a patch to Emacs.  However, I used
the set of strings described here:

Would it be a copyright problem?

Best,
