 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'))
       (range
         (symbol '0')
         (symbol '3')))
     (range
       (symbol '2')
       (symbol '1')))
   * set:
   <filteredset
     <filteredset
       <spanset- 0:4>,
       <spanset+ 0:4>>,
     <not
       <spanset+ 1:3>>>
   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'))

 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
   [255]
 
 topo.firstbranch should accept any kind of expressions:
 
   $ hg log -r 'sort(0, topo, topo.firstbranch=(book1))'
