RFA: Fix typo in description of absence_set

Hi Gerald, Hi Joseph,

  Please may I have approval to apply the following patch ?

  It does two things, both in the section in the md.texi file that
  describes the absence_set directive.  The first is to correct a typo
  in the first small example, (where the slots are in the wrong
  order).  The second this is to reword the end of one of paragraphs
  to make it slightly easier to understand.  I have run both of these
  changes past Vladamir Makarov and he thinks that they are OK.

	* doc/md.texi (Processor pipeline description): Correct first
	example of how the absence_set directive works.  Reword prior
	paragraph to make it slightly easier to read.
