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 with a newline in the generated config.

The .config file is a flat list of CONFIG options.
It does not represent menu structures at all.

I tested "make allyesconfig"
and the resulted outcome looks cheesy.



[1] Two blank lines in a row


---------->8-----------------
CONFIG_EFI_EARLYCON=y
CONFIG_IMX_SCU=y
CONFIG_IMX_SCU_PD=y

#
# Tegra firmware driver
#


CONFIG_HAVE_KVM=y
CONFIG_HAVE_KVM_IRQCHIP=y
CONFIG_HAVE_KVM_IRQFD=y
--------->8------------------------


[2] Some blank lines appended at the end of file

----------->8-------------
CONFIG_CPA_DEBUG=y
CONFIG_OPTIMIZE_INLINING=y
CONFIG_DEBUG_ENTRY=y
CONFIG_DEBUG_NMI_SELFTEST=y
CONFIG_X86_DEBUG_FPU=y
CONFIG_PUNIT_ATOM_DEBUG=y
CONFIG_UNWINDER_ORC=y
# CONFIG_UNWINDER_FRAME_POINTER is not set


---------->8-----------------



The readability of the .config could be improved somehow,
but this patch is not the right one.

Masahiro, thanks for having a look.
I've just sent v2 which does this task much better.

Best regards,
Alexander
