Bug#807810: Mention what if one wants to mark the bug forwarded to more than one place

[積丹尼 Dan Jacobson]

reassign 807810 bugs.debian.org
thanks
OK I'll reassign this bug, in the hope that on
https://www.debian.org/Bugs/server-control they will add some policy
statement about what to do when one wants to mark a bug forwarded to
more than one place, for whatever unexpected reason that might come up.

NB> I suppose at some point in the future the bugs server might change its
NB> behaviour. So one could argue that everything is already documented
NB> with this line in the bts man page:

NB> "For full details about the commands, see the BTS documentation.
NB> <https://www.debian.org/Bugs/server-control>"

NB> I don't see any particular reason to single out the forwarded command
NB> for extra documentation.
