feat: sanitizeNames
...
@Kha I am using `_shadowed.<idx>` suffix for marking variables that
have been shadowed. It is a bit verbose, but at least it is easy to
understand understand error messages such as
```
shadow.lean:4:0: error: type mismatch
h
has type
x._shadowed.1 = x._shadowed.1
but it is expected to have type
x = x
```
It is better than the old cryptic version
```
shadow.lean:4:0: error: type mismatch
h
has type
x = x
but it is expected to have type
x = x
```

fix: expandMatchDiscr cannot be a macro
...
The `matchType` created by the macro is bad for dependent pattern
matching. The `tst8` and `tst9` at `matchTac` failed to be elaborated
when using the macro.

feat: indented by
...
@Kha This one is not as useful as the indented `do`. When writing
interactive proofs I like the error message at the `}` showing the
resulting tactic state. We can simulate it using a `skip` in the end of the sequence :)
We remove the `skip` when the proof is done. Note that, the last `;`
is usually not part of the `by`. Example:
```lean
theorem ex (x y z : Nat) : y = z → y = x → x = z :=
fun _ _ =>
have x = y by apply Eq.symm; assumption; -- <<< the last `;` is part of the `have`
Eq.trans this (by assumption)
```

fix: remove duplicate error messages due to variable(s)

In Lean4, we re-elaborate `variable`(s) for each command, but we don't
want the error messages due to `variable` to appear in the log
multiple times.
