Earlier, incompatible command-line options used to be caught in
pick_commits after parse_args has parsed the options and populated the
options structure. Instead, hand over the responsibility of catching
incompatible command-line options to parse_args so that the program
can die early. Also write a verify_opt_compatible function to handle
incompatible options in a general manner.
