Status lines for Emacs and Vim have been added to Python sources so they'll be easier to edit using Python's preferred coding style. Some DNS helper functions have been broken up into multiple files. It's nice to have one function per file whenever possible, since that way we don't need -ffunction-sections. Another reason it's good to have small source files, is because the build will be enforcing resource limits on compilation and testing soon.
