infix/suffix resolution of ^ operator (issue2884):

 x^:y means (x^):y

  $ try --optimize '1^:2'
  (parent
    ('symbol', '1')
    (rangepre
      ('symbol', '2')))
  * optimized:
  (range
    (parentpost
      ('symbol', '1'))
    ('symbol', '2'))
  * set:
  <spanset+ 0:2>
  0

  2

  $ try --optimize '1^::2'
  (parent
    ('symbol', '1')
    (dagrangepre
      ('symbol', '2')))
  * optimized:
  (dagrange
    (parentpost
      ('symbol', '1'))
    ('symbol', '2'))
  * set:
  <baseset+ [0, 1, 2]>
  0

 x^:y should be resolved before omitting group operators

  $ try --optimize '1^(:2)'
  (parent
    ('symbol', '1')
    (group
      (rangepre
        ('symbol', '2'))))
  * optimized:
  (parent
    ('symbol', '1')
    (range
      ('string', '0')
      ('symbol', '2')))
  hg: parse error: ^ expects a number 0, 1, or 2
  [255]

 x^:y should be resolved recursively

  $ try --optimize 'sort(1^:2)'
  (func
    ('symbol', 'sort')
    (parent
      ('symbol', '1')
      (rangepre
        ('symbol', '2'))))
  * optimized:
  (func
    ('symbol', 'sort')
    (range
      (parentpost
        ('symbol', '1'))
      ('symbol', '2')))
  * set:
  <spanset+ 0:2>
  0
  1
  2

  $ try --optimize '(3^:4)^:2'
  (parent
    (group
      (parent
        ('symbol', '3')
        (rangepre
          ('symbol', '4'))))
    (rangepre
      ('symbol', '2')))
  * optimized:
  (range
    (parentpost
      (range
        (parentpost
          ('symbol', '3'))
        ('symbol', '4')))
    ('symbol', '2'))
  * set:
  <spanset+ 0:2>
  0
  1

  $ try --optimize '(3^::4)^::2'
  (parent
    (group
      (parent
        ('symbol', '3')
        (dagrangepre
          ('symbol', '4'))))
    (dagrangepre
      ('symbol', '2')))
  * optimized:
  (dagrange
    (parentpost
      (dagrange
        (parentpost

        ('symbol', '4')))
    ('symbol', '2'))
  * set:
  <baseset+ [0, 1, 2]>
  0
  1
  2

 x^ in alias should also be resolved

  $ try --optimize 'A' --config 'revsetalias.A=1^:2'
  ('symbol', 'A')
  * expanded:
  (parent
    ('symbol', '1')
    (rangepre
      ('symbol', '2')))
  * optimized:
  (range
    (parentpost
      ('symbol', '1'))
    ('symbol', '2'))
  * set:
  <spanset+ 0:2>
  0
  1
  2

  $ try --optimize 'A:2' --config 'revsetalias.A=1^'
  (range
    ('symbol', 'A')
    ('symbol', '2'))
  * expanded:
  (range
    (parentpost
      ('symbol', '1'))
    ('symbol', '2'))
  * optimized:
  (range
    (parentpost
      ('symbol', '1'))
    ('symbol', '2'))
  * set:
  <spanset+ 0:2>
  0
  1
  2

 but not beyond the boundary of alias expansion, because the resolution should
 be made at the parsing stage

  $ try --optimize '1^A' --config 'revsetalias.A=:2'
  (parent
    ('symbol', '1')
    ('symbol', 'A'))
  * expanded:
  (parent
    ('symbol', '1')
    (rangepre
      ('symbol', '2')))
  * optimized:
  (range
    (parentpost
      ('symbol', '1'))
    ('symbol', '2'))
  * set:
  <spanset+ 0:2>
  0
  1
  2
BROKEN: should be parsed as '1^(:2)'

ancestor can accept 0 or more arguments

  $ log 'ancestor()'
  $ log 'ancestor(1)'
