68143ca8ba chore: trace[...]! ==> trace[...] 
@Kha I think this one is a good change, there is no real reason for
using the `!` suffix here.

30ba56126b fix: missing case

142d6cbcbc chore: truncate error messages endPos 
@Kha, @Vtec234, @mhuisi:
This is a bit hackish, but it improves the usuability quite a bit in
VS Code. Without this hack, I often get huge blocks of "red squiggly lines".

4bbcd305b5 fix: disable implicit-lambdas when elaborating patterns 
@Kha, Jason's example on issue #337 suggests that injecting
implicit-lambdas while elaborating patterns is problematic.
The elaborator was injecting `fun {Γ} =>` before the
pattern variable `ftm`.
So, I disabled the implicit-lambda during pattern elaboration. I
didn't find an example where it would be useful.

see #337

5d3f0606d2 feat: include type of type in "mismatch errors" 
@Kha we do that in Lean 3. It helps when the error is due to incorrect universe levels.

BTW, I had to update `tests/lean/server/content_diag.json` since the
error message is different, but a few other stuff changed too.
Could you please take a look whether the test is still correct?
