feat(library/tactic/rewrite_tactic): try to fold nested recursive applications after unfolding a recursive function
...
See issue #692 .
The implementation still has some rough spots.
It is not clear what the right semantic is.
Moreover, the folds in e_closure could not be eliminated automatically.

fix(library/tactic): we must unfold untrusted macros when type checking intermediate results
...
Example: before this commit, the file librata/data/list/perm.lean would
not type check if the option -t 0 (trust level zero) was provided.
Reason: the intermediate term contained a macro, and macros are not
allowed at trust level zero.
