context: clarify that only one attempt is made to interpret changeid

We can now tell what type of revision specifier we have just by
looking at it (we no longer attempt to interpret it in one way after
the other -- that's now in scmutil.revsymbol()). Let's clarify this in
the code by swithing to if/elif.

Widening preserves parent of local commit

  $ cd ..
  $ hg clone -q --narrow ssh://user@dummy/upstream narrow3 --include d2 -r 2
  $ cd narrow3
  $ hg log -T "{if(ellipsis, '...')}{node|short}: {desc}\n"
  *: add d2/f (glob)
  ...*: add d1/f (glob)
  $ hg pull -q -r 3
  $ hg co -q tip
  $ hg pull -q -r 4
  $ echo local > d2/f
  $ hg ci -m local
  created new head
  $ hg tracked -q --addinclude d0 --addinclude d9

Widening preserves bookmarks

  $ cd ..
  $ hg clone -q --narrow ssh://user@dummy/upstream narrow-bookmarks --include d4
  $ cd narrow-bookmarks
  $ echo local > d4/f
  $ hg ci -m local
  $ hg bookmarks bookmark
  $ hg bookmarks
   * bookmark                  3:* (glob)
  $ hg -q tracked --addinclude d2
  $ hg bookmarks
   * bookmark                  5:* (glob)
  $ hg log -r bookmark -T '{desc}\n'
  local
