-\`Matchers' allow the completion code to play extra tricks when comparing
-the string on the command line with a possible match, as listed below.
-A list of different matchers can be given; each is tried until at least
-one possible completion is found.  The numbers given below show what is
-included in each element of the list; everything for 1 is tried at the same
-time, and if necessary everything for 2, etc.  If no matcher is set
-ordinary completion will be done at that point.  Elements from 1 to 4 can
-be set; empty trailing elements will be removed, and if nothing is set, the
-style will not be set.
+\`Matchers' compare the completion code with the possible matches in some
+special way.  Numbers in parentheses show matchers to be tried and the order.
+The same number can be assigned to different matchers, meaning apply at the
+same time.  Omit a sequence number to try normal matching at that point.
+A \`+' in the first line indicates the element is added to preceeding matchers
+instead of replacing them; toggle this with \`t'.  You don't need to set
+all four, or indeed any matchers --- then the style will not be set.
 
+   ($a_or_r)\
+   \`+' indicates add to previous matchers, else replace
 n. ($n_list)\
  No matchers; you may want to try this as the first choice.
