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. Suggested-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Petr Vorel <petr.vorel@gmail.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
