I like the general idea, but I would like to make the additional help
support optional. This has two reasons: 

 - ddb is very usefull even in tiny configurations where every kernel
   byte counts
 - people doing heavy kernel work might decide to not need the help
   a lot (or have the other machine, where they cross build from,
   easily available to run "man ddb")

Could you define a macro to declare the DDB command and make it just ignore
the help string parameter if compiled w/o the DDB_VERBOSE_HELP (or whatever
we'd call it) option?

i.e. change this

       { "mbuf", "Show number and status of mbuf's.",  db_mbuf_print_cmd,      
	0,      NULL },

to:

	DDB_DECLARE_SIMPLE_CMD("mbuf", "Show number and status of mbuf's.",
	    db_mbuf_print_cmd)

(and a non-SIMPLE variant if the "flags" or "more" field are filled in?)


And feel free to use other names, I'm not good at inventing them ;-}
