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.

==================================
Test for "orphan" type instability
==================================

This file gather test case around the "orphan" changeset instability. This
instability happens when a changesets has obsolete ancestors.

orphan parent is obsolete with a single successor
=================================================

Test orphan resolution for a changeset orphan because its parent is obsolete
with one successor.

  $ hg up "desc(_b)"
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

orphan parent is obsolete with a multiple successors (reversed order)
=====================================================================

Test orphan resolution for a changeset orphan because its parent is obsolete
with multiple successors on the same branch but in reverse order (cross-split).

  $ hg init test5
  $ cd test5
  $ mkcommits _a _b _c
  $ hg up "desc(_a)"
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ mkcommits bprimesplit1 bprimesplit2
  created new head
  $ hg prune "desc(_b)" -s "desc(bprimesplit1) + desc(bprimesplit2)" --split
  1 changesets pruned
  1 new orphan changesets
  $ hg up "desc(_a)"
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ mkcommits bsecondsplit1 bsecondsplit2
  created new head
  $ hg prune "desc(bprimesplit1)" -s "desc(bsecondsplit2)"
  1 changesets pruned
  1 new orphan changesets
