Message-Id: <200709152004.11930.strohel@gmail.com>

Subject: [PATCH v2] menuconfig: distinguish between selected-by-another options and comments
menuconfig currently represents options implied by another option ('select'
directive in Kconfig) by prefixing them with '---'. Unfortunately the same
notation is used for comments.
This patch changes notation of selected-by-another items by introducing 2 new
representations for implied options:
{*} or {M} for options selected by another modularized one, thus builtin or
module capable,
-*- or -M- for options that cannot be at the moment changed by user.
The idea is to represent actual capability of the option by braces (dashes)
around and to always report actual state by * or M inside.
Signed-off-by: Matěj Laitl <strohel@...il.com>

Changes since v1:
* introduce sym_get_minimal_value(), so that access to struct symbol is
abstracted.
* change also menuconfig's window header text to reflect the change. I'm still
not sure if the wording is optimal.
v1 was acked by Randy Dunlap, I'm not sure if it's appropriate to keep
Acked-by when patch changes. (teach me please)
