The built-in `bisect` code carries around some local state, in a somewhat futile attempt to keep things in a state that would be more amenable to libifying.

The `subcommand` series does not accommodate for such a local state, the signature `typedef int parse_opt_subcommand_fn(int argc, const char **argv, const char *prefix);` requires all pre-subcommand options to be parsed into global (or file-local, but not function-local) variables.

This implies that moving `cmd_bisect()` on top of the `subcommand` topic would require the `bisect` code to become less libifyable, which is an undesirable direction.

Ciao, Dscho
