column.

						*'conceallevel'* *'cole'*
'conceallevel' 'cole'	number	(default 0)
			local to window
	Determine how text with the "conceal" syntax attribute |:syn-conceal|
	is shown:

	Value		Effect ~
	0		Text is shown normally
	1		Each block of concealed text is replaced with one
			character.  If the syntax item does not have a custom
			replacement character defined (see |:syn-cchar|) the
			character defined in 'listchars' is used.
			It is highlighted with the "Conceal" highlight group.
	2		Concealed text is completely hidden unless it has a
			custom replacement character defined (see
			|:syn-cchar|).
	3		Concealed text is completely hidden.

	Note: in the cursor line concealed text is not hidden, so that you can
	edit and copy the text.  This can be changed with the 'concealcursor'
	option.

				*'confirm'* *'cf'* *'noconfirm'* *'nocf'*
'confirm' 'cf'		boolean	(default off)
			global
	When 'confirm' is on, certain operations that would normally
	fail because of unsaved changes to a buffer, e.g. ":q" and ":e",
	instead raise a dialog asking if you wish to save the current
	file(s).  You can still use a ! to unconditionally |abandon| a buffer.
	If 'confirm' is off you can still activate confirmation for one
	command only (this is most useful in mappings) with the |:confirm|
	command.
	Also see the |confirm()| function and the 'v' flag in 'guioptions'.

			*'copyindent'* *'ci'* *'nocopyindent'* *'noci'*
'copyindent' 'ci'	boolean	(default off)
			local to buffer
	Copy the structure of the existing lines indent when autoindenting a
	new line.  Normally the new indent is reconstructed by a series of
	tabs followed by spaces as required (unless |'expandtab'| is enabled,
	in which case only spaces are used).  Enabling this option makes the
	new line copy whatever characters were used for indenting on the
	existing line.  'expandtab' has no effect on these characters, a Tab
	remains a Tab.  If the new indent is greater than on the existing
	line, the remaining space is filled in the normal manner.
	See 'preserveindent'.

						*'cpoptions'* *'cpo'* *cpo*
'cpoptions' 'cpo'	string	(default "aABceFs_")
			global
	A sequence of single character flags.  When a character is present
	this indicates Vi-compatible behavior.  This is used for things where
	not being Vi-compatible is mostly or sometimes preferred.
	'cpoptions' stands for "compatible-options".
	Commas can be added for readability.
	To avoid problems with flags that are added in the future, use the
	"+=" and "-=" feature of ":set" |add-option-flags|.

	    contains	behavior	~
								*cpo-a*
		a	When included, a ":read" command with a file name
			argument will set the alternate file name for the
			current window.
								*cpo-A*
		A	When included, a ":write" command with a file name
			argument will set the alternate file name for the
			current window.
								*cpo-b*
		b	"\|" in a ":map" command is recognized as the end of
			the map command.  The '\' is included in the mapping,
			the text after the '|' is interpreted as the next
			command.  Use a CTRL-V instead of a backslash to
			include the '|' in the mapping.  Applies to all
			mapping, abbreviation, menu and autocmd commands.
			See also |map_bar|.
								*cpo-B*
		B	A backslash has no special meaning in mappings,
			abbreviations, user commands and the "to" part of the
			menu commands.  Remove this flag to be able to use a
			backslash like a CTRL-V.  For example, the command
			":map X \<Esc>" results in X being mapped to:
				'B' included:	"\^["	 (^[ is a real <Esc>)
				'B' excluded:	"<Esc>"  (5 characters)
								*cpo-c*
		c	Searching continues at the end of any match at the
			cursor position, but not further than the start of the
			next line.  When not present searching continues
			one character from the cursor position.  With 'c'
			"abababababab" only gets three matches when repeating
			"/abab", without 'c' there are five matches.
								*cpo-C*
		C	Do not concatenate sourced lines that start with
