Revert "kconfig-language: add to hints" 

This reverts commit 64b81ed7.

As Martin says about this paragraph:
    However, I can not reproduce this. The attached file contains both
    cases. [...] AFAICS, both versions behave equivalently. I suggest
    changing the documentation accordingly.

Kconfig symbol existence

~~~~~~~~~~~~~~~~~~~~~~~~

The following two methods produce the same kconfig symbol dependencies

but differ greatly in kconfig symbol existence (production) in the

generated config file.



case 1:



config FOO

	tristate "about foo"

	depends on BAR



vs. case 2:



if BAR

config FOO

	tristate "about foo"

endif



In case 1, the symbol FOO will always exist in the config file (given

no other dependencies).  In case 2, the symbol FOO will only exist in

the config file if BAR is enabled.
