Subject: [RFC v5 0/1] i-search navigation for mconf

Hello,

I reworked the prototype for the i-search navigation concept.  It is
now more thoroughly tested and hopefully not a waste of time to have a
look at it.

For the focus-sensitive help text, I modified the function
print_autowrap() and for now called it print_autowrap_fill().  It
could replace the old function but does a bit more work than it.

With this navigation concept, mconf's behavior (in i-search mode) is
quite different from the known one, most noticeably the need to switch
focus to the buttons to be able to use <y|n|m|space>.   Ideas are very
welcome.

Interesting in i-search mode is the ability to not only search item
strings, but also their selection marks.  So, one can search for items
selected as a module, for example.

Dirk

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.
