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:

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:
