kconfig: Terminate menu blocks with a comment in the generated config
Currently menu blocks start with a pretty header but end with nothing in the generated config. So next config options stick together with the options from the menu block. Let's terminate menu blocks in the generated config with a comment and a newline if needed. Example: ... CONFIG_BPF_STREAM_PARSER=y CONFIG_NET_FLOW_LIMIT=y # # Network testing # CONFIG_NET_PKTGEN=y CONFIG_NET_DROP_MONITOR=y # end of Network testing # end of Networking options CONFIG_HAMRADIO=y ...
