8b7dc4e03a feat(frontends/lean): apply eta-reduction in postprocessing step
Perhaps, we should add an option to disable this new feature.

Remark: this commit makes commit 46d418a redundant.
I'm keeping 46d418a because we may retract this commit in the future.

ff01774fd7 renaming(hit): rename type_quotient to quotient, and quotient to set_quotient
This renaming is because type_quotient is a nonstandard name.  I've had a discussion with Egbert
Rijke, Steve Awodey and Dan Licata, and the consensus for a better name was 'quotient'.  I had to
make changes in src/kernel/hits/hits.cpp, I renamed g_type_quotient* by g_hit_quotient* (to avoid
name clash the standard library quotient, although I don't know whether that name clash would
matter).

Comment from @lunaryorn (flycheck author):

"Please don't use an advice to increment error columns. Flycheck has
:error-filters and there is even a built-in one exactly for your use
case: :error-filter flycheck-increment-error-columsn. Generally never
use advises at all in libraries or modes. They are for user
configuration, or as a very last resort only."
