Patch 7.4.330

Problem:    Using a regexp pattern to highlight a specific position can be

	    slow.

Solution:   Add matchaddpos() to highlight specific positions efficiently.

  		available from |getmatches()|.	All matches can be deleted in

  		one operation by |clearmatches()|.

+ matchaddpos({group}, {pos}[, {priority}[, {id}]])		*matchaddpos()*

+ 		Same as |matchadd()|, but requires a list of positions {pos}

+ 		instead of a pattern. This command is faster than |matchadd()|

+ 		because it does not require to handle regular expressions and

+ 		sets buffer line boundaries to redraw screen. It is supposed

+ 		to be used when fast match additions and deletions are

+ 		required, for example to highlight matching parentheses.

+ 

+ 		The list {pos} can contain one of these items:

+ 		- A number.  This while line will be highlighted.  The first

+ 		  line has number 1.

+ 		- A list with one number, e.g., [23]. The whole line with this

+ 		  number will be highlighted.

+ 		- A list with two numbers, e.g., [23, 11]. The first number is

+ 		  the line number, the second one the column number (first

+ 		  column is 1).  The character at this position will be

+ 		  highlighted.

+ 		- A list with three numbers, e.g., [23, 11, 3]. As above, but

+ 		  the third number gives the length of the highlight in screen

+ 		  cells.

+ 		

+ 		The maximum number of positions is 8.

+ 

+ 		Example: >

+ 			:highlight MyGroup ctermbg=green guibg=green

+ 			:let m = matchaddpos("MyGroup", [[23, 24], 34])

+ <		Deletion of the pattern: >

+ 			:call matchdelete(m)

+ 

+ <		Matches added by |matchaddpos()| are returned by

+ 		|getmatches()| with an entry "pos1", "pos2", etc., with the

+ 		value a list like the {pos} item.

+ 		These matches cannot be set via |setmatches()|, however they

+ 		can still be deleted by |clearmatches()|.

+ 

  matcharg({nr})							*matcharg()*

  		Selects the {nr} match item, as set with a |:match|,

  		|:2match| or |:3match| command.
