Subject: [RFC v6 0/1] mconf: global i-search in menu structure

Hello,

version 6 of this RFC was mainly influenced by a discussion with Randy
Dunlap about a patch for i-search in nconf.

In that discussion I stated that it would be a lot of work to
implement a global i-search but while thinking about that statement
afterwards, I realized that most of the needed functionality is
already there in search_conf(), the search function for config
symbols.

The menu tree is converted in a flat menu to ease the implementation
of a cyclic i-search and the rest of the implementation does no longer
interfere so much with current menu handling.

Dirk

Changes in v6:

* The modification of the function print_autowrap() was reworked and
  is no longer a separate function.

* The i-search navigation was completely reworked and now works on the
  whole menu tree.

* Hotkeys are back, because they do not interfere that much with this
  version of i-search navigation.

Changes in v5:

* More thoroughly tested code

* Hotkey navigation concept completely dropped

* Printable characters except special ones form the search string

* Focus-sensitive help text above menu

* DEL erases search string

* Matching string is highlighted in selected menu item

* README help text adjusted

Changes in v4:

* Prototype: consequent i-search navigation concept

Changes in v3:

* Use current git tree to make the patch apply.

* Eliminate debugging output to stderr.

Changes in v2:

* Additionally to CTRL-s, \ can be used to start isearch.

* Raw mode is off by default an can be enabled by an environment
  variable MENUCONFIG_RAW_MODE.

* I also added a variable for toggling raw mode but did not implement
  anything else.

* The isearch indicator is now displayed as soon as isearch is
  started.

* Any key except \, CTRL-s, alphanumeric characters and space
  terminates isearch and -- except ESC ESC -- is further processed,
  e.g. ENTER terminates isearch and is then used to navigate into a
  submenu.

* Problems with mismatches and matches above the current position were
  fixed.
