Test order of revisions in compound expression
----------------------------------------------

The general rule is that only the outermost (= leftmost) predicate can
enforce its ordering requirement. The other predicates should take the
ordering defined by it.

 'A & B' should follow the order of 'A':

  $ log '2:0 & 0::2'
  2
  1
  0

 'head()' combines sets in right order:

  $ log '2:0 & head()'
  2
  1
  0

 'x:y' takes ordering parameter into account:

  $ try -p optimized '3:0 & 0:3 & not 2:1'
  * optimized:
  (difference
    (and
      (range
        ('symbol', '3')
        ('symbol', '0')
        define)
      (range
        ('symbol', '0')
        ('symbol', '3')
        follow)
      define)
    (range
      ('symbol', '2')
      ('symbol', '1')
      any)
    define)
  * set:
  <filteredset
    <filteredset
      <spanset- 0:3>,
      <spanset+ 0:3>>,
    <not
      <spanset+ 1:2>>>
  3
  0

 'a + b', which is optimized to '_list(a b)', should take the ordering of
 the left expression:

  $ try --optimize '2:0 & (0 + 1 + 2)'
  (and
    (range
      ('symbol', '2')
      ('symbol', '0'))
    (group
      (or
        (list
          ('symbol', '0')
          ('symbol', '1')
          ('symbol', '2')))))
  * optimized:
  (and
    (range
      ('symbol', '2')
      ('symbol', '0')
      define)
    (func
      ('symbol', '_list')
      ('string', '0\x001\x002')
      follow)
    define)
  * set:
  <filteredset
    <spanset- 0:2>,
    <baseset [0, 1, 2]>>
  2
  1
  0

 'A + B' should take the ordering of the left expression:

  $ try --optimize '2:0 & (0:1 + 2)'
  (and
    (range
      ('symbol', '2')
      ('symbol', '0'))
    (group
      (or
        (list
          (range
            ('symbol', '0')
            ('symbol', '1'))
          ('symbol', '2')))))
  * optimized:
  (and
    (range
      ('symbol', '2')
      ('symbol', '0')
      define)
    (or
      (list
        (range
          ('symbol', '0')
          ('symbol', '1')
          follow)
        ('symbol', '2'))
      follow)
    define)
  * set:
  <filteredset
    <spanset- 0:2>,
    <addset
      <spanset+ 0:1>,
      <baseset [2]>>>
  2

      follow)

      define)
    define)

 for 'A & (op)(B)', 'B' should not be affected by the order of 'A':

  $ try --optimize '2:0 & (1 + 0 + 2):(0 + 2 + 1)'
  (and
    (range
      ('symbol', '2')
      ('symbol', '0'))
    (range
      (group
        (or
          (list
            ('symbol', '1')
            ('symbol', '0')
            ('symbol', '2'))))
      (group
        (or
          (list
            ('symbol', '0')
            ('symbol', '2')
            ('symbol', '1'))))))
  * optimized:
  (and
    (range
      ('symbol', '2')
      ('symbol', '0')
      define)
    (range
      (func
        ('symbol', '_list')
        ('string', '1\x000\x002')
        define)
      (func
        ('symbol', '_list')
        ('string', '0\x002\x001')
        define)
      follow)
    define)
  * set:
  <filteredset
    <spanset- 0:2>,
    <baseset [1]>>
  1

 'A & B' can be rewritten as 'B & A' by weight, but that's fine as long as
 the ordering rule is determined before the rewrite; in this example,
 'B' follows the order of the initial set, which is the same order as 'A'
 since 'A' also follows the order:

  $ try --optimize 'contains("glob:*") & (2 + 0 + 1)'
  (and
    (func
      ('symbol', 'contains')
      ('string', 'glob:*'))
    (group
      (or
        (list
          ('symbol', '2')
          ('symbol', '0')
          ('symbol', '1')))))
  * optimized:
  (and
    (func
      ('symbol', '_list')
      ('string', '2\x000\x001')
      follow)
    (func
      ('symbol', 'contains')
      ('string', 'glob:*')
      define)
    define)
  * set:
  <filteredset
    <baseset+ [0, 1, 2]>,
    <contains 'glob:*'>>
  0
  1
  2

 and in this example, 'A & B' is rewritten as 'B & A', but 'A' overrides
 the order appropriately:

  $ try --optimize 'reverse(contains("glob:*")) & (0 + 2 + 1)'
  (and
    (func
      ('symbol', 'reverse')
      (func
        ('symbol', 'contains')
        ('string', 'glob:*')))
    (group
      (or
        (list
          ('symbol', '0')
          ('symbol', '2')
          ('symbol', '1')))))
  * optimized:
  (and
    (func
      ('symbol', '_list')
      ('string', '0\x002\x001')
      follow)
    (func
      ('symbol', 'reverse')
      (func
        ('symbol', 'contains')
        ('string', 'glob:*')
        define)

topographical sorting can't be combined with other sort keys, and you can't
use the topo.firstbranch option when topo sort is not active:

  $ hg log -r 'sort(all(), "topo user")'
  hg: parse error: topo sort order cannot be combined with other sort keys
  [255]

  $ hg log -r 'sort(all(), user, topo.firstbranch=book1)'
  hg: parse error: topo.firstbranch can only be used when using the topo sort key

topo.firstbranch should accept any kind of expressions:
