In printing, factorizing "match" clauses with same right-hand side.
Moreover, when there are at least two clauses and the last most
factorizable one is a disjunction with no variables, turn it into a
catch-all clause.
Adding options
Unset Printing Allow Default Clause.
to deactivate the second behavior, and
Unset Printing Factorizable Match Patterns.
to deactivate the first behavior (deactivating the first one
deactivates also the second one).
E.g. printing
match x with Eq => 1 | _ => 0 end
gives
match x with
| Eq => 1
| _ => 0
end
or (with default clause deactivates):
match x with
| Eq => 1
| Lt | Gt => 0
end
More to be done, e.g. reconstructing multiple patterns in Nat.eqb...
