If we've set the bh_type to something besides BLACKHOLE_UNSPEC

RTN_UNREACHABLE or RTN_PROHIBIT then just trust that
the nexthop is just what it is and set accordingly.

vty_frame() can be used to reduce the amount of output produced by "show

lib: fix rare bug in ambiguous command resolution
In certain situations, the CLI matcher would not handle ambiguous
commands properly. If it found an ambiguous result in a lower subgraph,
the ambiguous result would not correctly propagate up to previous frames
in the resolution DFS as ambiguous; instead it would propagate up as a
non-match, which could subsequently be overridden by a partial match.
Example CLI space:
show ip route summary
show ip route supernet-only
show ipv6 route summary
Entering `show ip route su` would result in an ambiguous resolution for
the `show ip route` subgraph but would propagate up to the `show ip`
subgraph as a no-match, allowing `ip` to partial-match `ipv6` and
execute that command.
In this example entering `show ip route summary` would disambiguate the
`show ip` subgraph. So this bug would only appear when entering input
that caused ambiguities in at least two parallel subgraphs.
