kconfig: make "Selected by:" and "Implied by:" readable
Reverse dependency expressions can get rather unwieldy, especially if
a symbol is selected by more than a handful of other symbols. I.e. it's
possible to have near endless expressions like:
A && B && !C || D || F && (G || H) || [...]
Chop these expressions into actually readable chunks:
- A && B && !C
- D
- F && (G || H)
- [...]
I.e. transform the top level OR tokens into newlines and prepend each
line with a minus. This makes the "Selected by:" and "Implied by:" blurb
much easier to read. This is done only if there is more than one top
level OR. "Depends on:" and "Range :" were deliberately left as they are.
Based on idea from Paul Bolle.
