Lemon update 2015-01-01 19:11:22 on branch trunk

Browse source 
- Enhance the "lemon" executable so that it ignores -f, -W, -O, and -I command-line options. This permits most of the same options that are passed to the compiler to also be harmlessly passed to lemon, and thus simplifies makefiles. (user: drh)
