Hei hei,

> +# vim: syntax=kconfig

is there any reason you chose 'syntax' over 'filetype'? I probably did
not fully understand the differences between those two Vim commands,
but the modeline in my custom *.in is like this:

# vim: ft=kconfig noet tw=72

noexpandtab is useful to keep the whitespace like in the other
rules/*.in files and textwidth=72 is my personal choice for easier
wrapping.
