Subject: [PATCH] Factor handle_bp_command into pieces: - Bug fix: return a
syntax error if the wrong number of arguments are given. - Add
handle_bp_command_list() and handle_bp_command_set(). - Use temporary addr
variable to eliminate redundant strtoul() calls. - Place variable
declarations at their point of first use.
