  Initial take on builtin drivers with multiline This extends the diff driver parser to support multiline driver definitions along with ! prefixing for negated matches. This brings the driver function pattern parsing in line with core Git. This also adds an internal table of driver definitions and a fallback code path that will look in that table for diff drivers that are set with attributes without having a definition in the config file. Right now, I just populated the table with a kind of simple HTML definition that is similar to the core Git def.
