prune: spell --successor flag without any unnecessary shortcuts

If a user wants to spell out -s, it makes sense to allow that. Before this
patch, prune would complain that --successor is not a recognized option.
Obviously people don't usually need to spell --successors by hand thanks to
shell completion (at least for Bash) using debugcomplete to see all available
flags, so this patch doesn't bring any need for more typing.

And thanks to Mercurial understanding shortened forms of command-line flags as
long as they are unambiguous, the old-style `--succ` flags still work normally,
and there are tests that use them. But two tests now use the full form to
demonstrate that both ways work.

+====================================================
+Tests the resolution of content divergence: metadata
+====================================================

This file intend to cover cases focused around meta data merging.

Setup
-----

  $ cat >> $HGRCPATH <<EOF
  > [alias]
  > glog = log -GT "{rev}:{node|short} {desc|firstline}\n {phase} {instabilities}\n\n"
  > [phases]
  > publish = False
  > [extensions]
  > rebase =
  > EOF
  $ echo "evolve=$(echo $(dirname $TESTDIR))/hgext3rd/evolve/" >> $HGRCPATH

Check we preserve the author properly
-------------------------------------

Testing issue6113 to make sure that content-divergence resolution don't
replace initial author with the user running the resolution command:

  $ hg init userfoo
  $ cd userfoo
  $ unset HGUSER
  $ echo "[ui]" >> ./.hg/hgrc
  $ echo "username = foo <[e-mail]>" >> ./.hg/hgrc
  $ for ch in a b c; do
  > echo $ch > $ch;
  > hg add $ch;
  > hg ci -m "added "$ch;
  > done;

  $ cd ..
  $ hg init userbar
  $ cd userbar
  $ unset HGUSER
  $ echo "[ui]" >> ./.hg/hgrc
  $ echo "username = bar <[e-mail]>" >> ./.hg/hgrc
  $ hg pull ./../userfoo -q

  $ cd ../userfoo
  $ hg up -r "desc('added b')"
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo c > c
  $ echo e > e
  $ hg add c e
  $ hg ci -m "added c e"
  created new head

  $ hg up -r "desc('added b')"
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ echo cc > c
  $ hg add c
  $ hg ci -m "added c"
  created new head

  $ hg prune -r "min(desc('added c'))" -s "desc('added c e')"
  1 changesets pruned
  $ hg prune -r "min(desc('added c'))" -s "max(desc('added c'))" --hidden
  1 changesets pruned
  2 new content-divergent changesets

  $ hg glog
  @  4:6c06cda6dc99 added c
  |   draft content-divergent
  |
  | *  3:0c9267e23c9d added c e
  |/    draft content-divergent
  |
  o  1:1740ad2a1eda added b
  |   draft
  |
  o  0:f863f39764c4 added a
      draft
  

  $ cd ../userbar
  $ hg pull ./../userfoo -q
  2 new content-divergent changesets

  $ hg evolve --content-divergent --any
  merge:[3] added c e
  with: [4] added c
  base: [2] added c
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

Make sure resultant cset don't replace the initial user with user running the command:
  $ hg log -r tip
  changeset:   5:443bd2972210
  tag:         tip
  parent:      1:1740ad2a1eda
  user:        foo <[e-mail]>
  date:        Thu Jan 01 00:00:00 1970 +0000
  summary:     added c e
  
  $ cd ..

Testing the three way merge logic for user of content divergent changesets
--------------------------------------------------------------------------

  $ hg init mergeusers
  $ cd mergeusers
  $ for ch in a b c; do
  > touch $ch
  > hg add $ch
  > hg ci -m "added "$ch
  > done;

  $ hg amend -m "updated c"
  $ hg up -r 'desc("added c")' --hidden -q
  updated to hidden changeset 2b3c31fe982d
  (hidden revision '2b3c31fe982d' was rewritten as: 464e35020fd0)
  working directory parent is obsolete! (2b3c31fe982d)
  $ echo coco > c

1) when one user is different wrt base
--------------------------------------

Insert a diverging author name:
  $ hg amend -u 'foouser'
  2 new content-divergent changesets

Run automatic evolution:
  $ hg evolve --content-divergent
  merge:[3] updated c
  with: [4] added c
  base: [2] added c
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  working directory is now at 932d6ceb7672

  $ hg log -r tip | grep "^user"
  user:        foouser

  $ hg strip . -q --config extensions.strip=
  2 new content-divergent changesets

2) when both the user are different wrt base
--------------------------------------------

  $ hg up -r 'max(desc("updated c"))'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg amend -u 'baruser'

Run automatic evolution:
  $ hg evolve --content-divergent
  merge:[4] added c
  with: [5] updated c
  base: [2] added c
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  working directory is now at 202a770d8c1f

  $ hg log -r tip | grep "^user"
  user:        baruser, foouser

  $ cd ..
