      Use symbol ∗ for separating conjunction.
      
      The old choice for ★ was a arbitrary: the precedence of the ASCII asterisk * was fixed at a wrong level in Coq, so we had to pick another symbol. The ★ was a random choice from a unicode chart.
      
      The new symbol ∗ (as proposed by David Swasey) corresponds better to conventional practise and matches the symbol we use on paper.

      Change the way we handle view shifts in post-conditions
      
      Now we try to avoid adding them unnecessarily, so we don't have to remove them automatically any more.
      
      The overall tally in the proofs (i.e., excluding changes in proof mode and lifting lemmas) is: 14 removed `iModIntro` (and equivalent tactics), 7 insertions of `wp_fupd`. So it seems we actually more often do not need that final update than we do need it. Not to mention this also simplifies the lifting lemmas and the proof mode, doing less unnecessary work (adding updates and then removing them again).
      
      On the minus side, *if* the update is missing, unexperienced users will have a hard time figuring out what to do. The change typically needs to be made at the beginning of the proof, the problem only surfaces at the end. This could be mitigated by providing a tactic for proving texan triples that does the `wp_fupd` (and the introducing the `\Phi`). While this would re-add most of the 14 removed `iModIntro`, we could still keep the simplified lifting lemmas and proof mode.
