Hi Michal,

Perhaps my dislike of this element of the grammar won here. There are
probably better ways to enforce proper use of "depends on".

Well, a grammar that allows one of its keywords to be written in
different ways makes style and grammar issues overlap. Whatever. I guess
it's just me being annoyed with writing
git grep -w "depends\s\+on\s\+FOO"
instead of
git grep -w "depends on FOO"
Ditto for writing a parser for Kconfig files. (Real world examples are
more complicated, but you catch my drift.)
