take parameter. Now it is set to NULL at default case.

Is there a reason for this to be in a different patch? I mean, why don't
you squash this into the previous patch?
Actually, I guess that you could skip the spaces after the
search_dispatch_table() call (using p) and drop p1. But please test it
before doing so :)
Otherwise series looks good to me.

Markus suggest to do it and I think this make things clear. I am OK
to merge it and drop p1.

Misunderstanding, sorry. My point was we skip over whitespace twice:
first here, and then again in monitor_parse_command(). Quote:
The check whether non-space characters follow is awkward. We need
it only because we want to handle "@cmdline is blank" differently
than "it can't be parsed", but monitor_parse_command() returns NULL
for both cases.
Merely an observation, not a request to do anything about it in this
series:
If we care, we can try to do better in a follow-up patch.
A possible way to do better is to have a handler for command "", to be
invoked for entirely blank lines. In table info_cmds, the handler would
be do_info_help. Then prefix commands don't need their handler anymore
(it's in the sub_table), and sub_table can go into the mhandler union.
We'd need to suppress the "unknown command" error for cmdname "".
If this isn't clear, but you want to understand it, I can write a patch
on top.
> and I think this make things clear. I am OK

I'm not sure it makes things clearer. It makes behavior of "info"
without argument change twice in the series, though, in the preceding
patch, and in this one. I think I agree with Luiz it's better to squash
the two together again.

That was my point in my second paragraph (which cut out).

Thanks for the declaration. Have a handler for command "" seems good,
but need a careful check about the parsing code since '\0' is a key
value. *sub_table plays an extra role of tagging if it have sub-commands
so I think it is better to not folder it into mhandler union.

Because mon_cmds may use info_cmds, so adjust the declare sequence
of them.

Now info command takes a table of sub info commands,
and changed do_info() to do_info_help() to do help funtion
only.
Note that now "info <unknown-topic>" returns error instead
of list of info topics.
