rhg: add support for calling `rhg cat` without a revision

Turns out the necessary pieces were there already.
Like the Python implementation, we default to the first parent of the dirstate.

subsetparents: p1/p2 order
-------------------------

  $ cd named-branch-order

Parents should be sorted in p1/p2 order since p1 is likely to belong to
the same named branch:

  $ hg log -Gq -T '{rev} {tags}: {subsetparents(rev, revset("0+1+2+6"))}\n' -r '0+1+2+6'
  o    6 : 2 1 0
  :\
  : \
  : :\
  : : o  2 :
  : :
  : o  1 :
  :
  o  0 :
  

  $ hg log -Gq -T '{rev} {tags}: {subsetparents(rev, revset("0+1+2+6+10"))}\n' -r '0+1+2+6+10'
  @    10 tip: 6
  :\
  : o    6 : 2 1 0
  :/:\
  : : o  2 :
  : :
  o :  1 :
   /
  o  0 :
  

And p1 path should be selected if both p1/p2 paths exist:

  $ hg log -Gq -T '{rev} {tags}: {subsetparents(rev, revset("0+1+2+10"))}\n' -r '0+1+2+10'
  @    10 tip: 1 2 0

  o :  1 :

  o  0 :
