graceful restart command not shown in context help

[Christoph]

Hello,

(for some unknown reason I'm not getting any emails from this mailing
list even though I'm subscribed, please keep me in CC if you reply thanks!)

The NEWS entry for BIRD 2.0.5 mentions the graceful restart command:

https://gitlab.labs.nic.cz/labs/bird/blob/master/NEWS :> Version 2.0.5
(2019-08-01)
[...]
>   o Graceful restart command

but I didn't see it in the "?" output so I assumed it does not exist:

birdc
BIRD 2.0.6 ready.

quit                                           Quit the client

down                                           Shut the daemon down

By using "g<tab>", auto-completion revealed the existence of the command
and it works as intended.

bird> graceful restart
Graceful restart requested
Connection closed by server

Would be great to add it to the interactive help output so more people
can find out about it by using "?".

thanks!
