obslog: use singular name "succnode" for each element of {succnodes} The name that we pass for formatlist() is the name of each element. After this patch, you'll write '{succnodes % "{succnode}"}' instead of the confusing '{succnodes % "{succnodes}"}' (where the two "succnodes" refer to different things. Users can write templates that are compatible across this change by using e.g. '{succnodes % "{if(succnode, succnode, succnodes)}"}'.

Quitting an evolve in the middle (via ctrl-c or something) can leave things in a
weird intermediate state where hg thinks we're in the middle of an update
operation (or even just leave the 'merge' directory around without actually
indicating we're in the middle of *any* operation).

  $ hg ci -qAm apricot

  $ echo banana > b
  $ hg ci -qAm banana

Let's go back to amend 0 and make an orphan out of 1 (and a merge conflict to
test with)

  $ hg up -q 0
  $ echo blueberry > b
  $ hg l
  o  1 banana

  @  0 apricot
  
  $ hg ci --amend -qAm 'apricot and blueberry'
  1 new orphan changesets
  $ hg l
  @  2 apricot and blueberry
  
  *  1 banana

  x  0 apricot
  

  $ hg evolve --update --config hooks.precommit=false --config ui.merge=:other
  move:[1] banana
  atop:[2] apricot and blueberry
