Yes, "non-blank lines added/changed" seems preferable, simply because it
is clear and unambiguous.

 - I think Richard may have implied that a line with a symbol is a
   sufficient condition for nontriviality, but it isn't clear if
   intended it to be a necessary condition. I suspect he meant
   "sufficient", but I think many people would interpret it as a
   "necessary" condition.

 - The meaning of "symbol" is not immediately clear in non-lisp code
   such as C, makefiles, scripts, etc.

 - If a commit completely rewrites a long comment or doc string, should
   it be considered "trivial" for the purposes of copyright?
