Yes, we should change this. I'm inclined to think the should die with an
error on invalid syntax. Would that be too strict?
Anyhow, seems to work as advertised:
$ make ARCH=arm menuconfig
[...]
sound/soc/intel/Kconfig:40:warning: ignoring unsupported character '\'
sound/soc/intel/Kconfig:70:warning: ignoring unsupported character '\'
arch/arm/Kconfig.debug:1268:warning: ignoring unsupported character '>'
The soc/intel warnings are for doubled line continuations! You've earned
a Reported-by:, I guess.

But this hunk looks unrelated. Is this needed?
