89e860ac8b doc(init/core): Document init_quotient in lean 
This way people can search for "constant quot" and find it in the lean source. Plus the init_quotient command only occurs once, so this way people know what it means.

4ae2f87bc8 refactor(init/meta/tactic): use dite instead of cases in by_cases 
This fixes the issue in PR #1752 by using `dite`, which is essentially nondependent cases, so that the decidable instances are not substituted.

776b440d55 fix(library/constructions/projection): fix macro expansion 
Thanks to @fpvandoorn for noticing this issue in Lean 2!  We encountered
this situation when the inferred type of the projection argument did not
reduce to the structure type with the current transparency setting of
the type context.

9afb53fad5 feat(kernel/expr): allow metavariables to have user-facing names 
We need this feature for:
1) Defining nonlinear search patterns. Example: (?m <= ?m + 1)
2) Preprocessing recursive equations and support the pattern
refinement approach used in Agda. Example: in Agda, they accept
```
def append {A : Type} : Π (m n : nat), Vec A m -> Vec A n -> Vec A (m + n)
| m n nil            ys := ys
| m n (cons m' x xs) ys := cons x (append m' n xs ys)
```
These equations have to be refined. For example, `m` has to be
replaced with `0` (in the first equation), and `succ m'` in the
second. To implement this kind of refinement, we need to convert
the pattern variables (local constants) into metavariables during
elaboration. Then, the unassigned metavariables become local constants
again. This preprocessing step will fix some of the issues on #1594.
To completely fix #1594, we will need yet another preprocessing step
which will implement "complete transition" used in the equation
compiler before we start elim_match.cpp

9367e94900 fix(frontends/lean/pp): hide proof terms in non-proofs by default 
This is mainly to reduce clutter.  Proof term printing can still be
forced using the `pp.proofs` option.

37d9e03cc1 feat(frontends/lean/pp): show substituted expressions for delayed abstractions 
@leodemoura I tried to look up the unique names in the local context,
but this pretty much always fails.  AFAICT we never remember the local
context when pretty-printing expression texts.

b093b3c1ee chore(extras/depgraph): remove leandeps 
There is no reason to implement this tool in Python anymore.
If someone wants (I don't), they should do it in Lean, and store it as
a Lean package in a separate git repository.
Closes #1744

Main problem with this commit: the counter-examples for non-exhaustive matches will be
cryptic when using nested inductive types.
