Thanks for your feedback Roman.

What about something like this?

	if (sym && sym->name && !(sym->flags & SYMBOL_CONST)) {
+		bool isNotSelected = (print_filter(sym_get_string_value(sym)) == "n");
+		if (isNotSelected) {
+			const QColor c(palette().disabled().text());
+			*text += "<font color=\"" + c.name() + "\">";
+		}
		*text += QString().sprintf("<a href=\"s%p\">", sym);
		*text += str2;
		*text += "</a>";
+		if (isNotSelected)
+			*text += "</font>";


It it's ok for you I can resend a proper patch along the above lines.

No it is not intended like a 'click me to enable this option', just as
a monitor of current option value.

BTW we can have a disabled symbol in the dependency list of a
currently enabled option if this is preceded by a '!'. So that in this
case you probably would not want to click anywhere.
