src/config.c: Keep formatting and comments
Switch to using the new config_file_walk() helper in config_save() and update existing configuration variables instead of blindly overwriting the existing configuration file. Note: This breaks configuration setting storage if one or more settings are missing in the configuration file. We need to refactor our parser and serialization routines another time before this can be implemented properly, though. Signed-off-by: Lukas Fleischer <calcurse@cryptocrack.de>
