* I see, thank you for the clarification. Reading this language reference and seeing the config entries consistently using indentation in Kconfig files, I mistook it as language syntax.

* Maybe it'll help to explicitly specify that indentation is not the Kconfig language syntax.

* Got it. In that case, to confirm: are there any input cases which are erroneous according to the Kconfig language syntax? Because even config entries ending with an 'EOF' are not flagged as an error.


* Last to confirm: is 'kconfig-language.html' reference for the Kconfig langauge as implemented in kernel OR it is the general language reference that applies to all Kconfig files across all projects? Because non-kernel projects also seem to use Kconfig files.


Thank you.
