the pattern may match more than one
				line, which makes the match depend on where
				Vim starts searching for the pattern.  You
				need to make sure syncing takes care of this.

	Example (match a character constant): >
  :syntax match Character /'.'/hs=s+1,he=e-1

DEFINING REGIONS	*:syn-region* *:syn-start* *:syn-skip* *:syn-end*
							*E398* *E399*
:sy[ntax] region {group-name} [{options}]
		[matchgroup={group-name}]
		[keepend]
		[extend]
		[excludenl]
		start={start-pattern} ..
		[skip={skip-pattern}]
		end={end-pattern} ..
		[{options}]

	This defines one region.  It may span several lines.

	{group-name}		A syntax group name such as "Comment".
	[{options}]		See |:syn-arguments| below.
	[matchgroup={group-name}]  The syntax group to use for the following
				start or end pattern matches only.  Not used
				for the text in between the matched start and
				end patterns.  Use NONE to reset to not using
				a different group for the start or end match.
				See |:syn-matchgroup|.
	keepend			Don't allow contained matches to go past a
				match with the end pattern.  See
				|:syn-keepend|.
	extend			Override a "keepend" for an item this region
				is contained in.  See |:syn-extend|.
	excludenl		Don't make a pattern with the end-of-line "$"
				extend a containing match or item.  Only
				useful for end patterns.  Must be given before
				the patterns it applies to. |:syn-excludenl|
	start={start-pattern}	The search pattern that defines the start of
				the region.  See |:syn-pattern| below.
	skip={skip-pattern}	The search pattern that defines text inside
				the region where not to look for the end
				pattern.  See |:syn-pattern| below.
	end={end-pattern}	The search pattern that defines the end of
				the region.  See |:syn-pattern| below.

	Example: >
  :syntax region String   start=+"+  skip=+\\"+  end=+"+
<
	The start/skip/end patterns and the options can be given in any order.
	There can be zero or one skip pattern.	There must be one or more
	start and end patterns.  This means that you can omit the skip
	pattern, but you must give at least one start and one end pattern.  It
	is allowed to have white space before and after the equal sign
	(although it mostly looks better without white space).

	When more than one start pattern is given, a match with one of these
	is sufficient.	This means there is an OR relation between the start
	patterns.  The last one that matches is used.  The same is true for
	the end patterns.

	The search for the end pattern starts right after the start pattern.
	Offsets are not used for this.	This implies that the match for the
	end pattern will never overlap with the start pattern.

	The skip and end pattern can match across line breaks, but since the
	search for the pattern can start in any line it often does not do what
	you want.  The skip pattern doesn't avoid a match of an end pattern in
	the next line.	Use single-line patterns to avoid trouble.

	Note: The decision to start a region is only based on a matching start
	pattern.  There is no check for a matching end pattern.  This does NOT
	work: >
		:syn region First  start="("  end=":"
		:syn region Second start="("  end=";"
<	The Second always matches before the First (last defined pattern has
	higher priority).  The Second region then continues until the next
	';', no matter if there is a ':' before it.  Using a match does work: >
		:syn match First  "(\_.\{-}:"
		:syn match Second "(\_.\{-};"
<	This pattern matches any character or line break with "\_." and
	repeats that with "\{-}" (repeat as few as possible).

							*:syn-keepend*
	By default, a contained match can obscure a match for the end pattern.
	This is useful for nesting.  For example, a region that starts with
	"{" and ends with "}", can contain another region.  An encountered "}"
	will then end the contained region, but not the outer region:
	    {		starts outer "{}" region
		{	starts contained "{}" region
		}	ends contained "{}" region
	    }		ends outer "{} region
