	CONCEAL -- the best mode.
		For this, your vim must have +conceal.  A typical way to get the
		conceal feature:

		* cd ..wherever../vim72/
		* wget http://vince.negri.googlepages.com/conceal-ownsyntax.diff
		* patch -p0 < conceal-ownsyntax.diff
		* make distclean
		* configure --with-features=huge
		* make
		* make install
	
	Normal: -- ansi escape sequences themselves are Ignore'd~
		Ansi escape sequences have the expected effect on subsequent
		text, but the ansi escape sequences themselves still take up
		screen columns.  The sequences are displayed using "Ignore"
		highlighting; depending on your colorscheme, this should either
		make the sequences blend into your background or be visually
		suppressed.  If the sequences aren't suppressed, you need to
		improve your colorscheme!

	USAGE~
		:AnsiEsc   -- toggles Ansi escape sequence highlighting
		:AnsiEsc!  -- rebuilds highlighting for new/removed three
		              or more element Ansi escape sequences.
	
	RESULT~
		Ansi escape sequences become concealed or ignored (depending
		on whether your vim supports Negri's conceal mode), and their
		effect on subsequent text is emulated with Vim's syntax
		highlighting.

		Syntax highlighting for one and two element codes are
		hard-coded into AnsiEsc.vim.  There are too many possibilities
		for three or more element codes; these are supported by
		examining the file for such sequences and only building syntax
		highlighting rules for such sequences as are actually present
		in the document.

	EXAMPLE~

		You'll want to use   :AnsiEsc   to see the following properly!
		(using Vince Negri's conceal option or vim 7.3)

3. AnsiEsc History					*AnsiEsc-history* {{{1
  v12	Jul 23, 2010	* changed conc to |'cole'| to correspond to vim 7.3's
			  change
	Aug 10, 2010	* (Rainer M Schmid) changed conceallevel setting to
			  depend on whether the version is before vim 7.3;
			  for 7.3, also sets concealcursor
			* Restores conc/cole/cocu settings when AnsiEsc is
			  toggled off.
	Dec 13, 2010	* Included some additional sequences involving 0
  v11	Apr 20, 2010	* AnsiEsc now supports enabling/disabling via a menu
			* <esc>[K and <esc>[00m now supported (as
			  grep --color=always   issues them)
  v10   May 06, 2009	* Three or more codes in an ANSI escape sequence are
			  supported by building custom syntax and highlighting
			  commands.
	May 20, 2009	* cecutil bugfix
  v9    May 12, 2008    * Now in plugin + autoload format.  Provides :AnsiEsc
                          command to toggle Ansi-escape sequence processing.
	Jan 01, 2009	* Applies Ignore highlighting to extended Ansi escape
			  sequences support 256-colors.
	Mar 18, 2009    * Includes "rapid blink" ansi escape sequences.  Vim
			  doesn't have a blinking attribute, so such text uses
			  "standout" for vim and "undercurl" for gvim.
  v8	Aug 16, 2006	* Uses undercurl, and so is only available for vim 7.0
  v7  	Dec 14, 2004	* Works better with vim2ansi output and Vince Negri's
			  conceal patch for vim 6.x.
  v2	Nov 24, 2004	* This version didn't use Vince Negri's conceal patch
			  (used Ignore highlighting)
