(less sanity checks, no impact on the undo stack).
Suitable e.g. for queries, or for the Set/Unset
of display options that coqide performs all the time.
- The 2nd flag controls the verbosity.
- The returned string contains the messages produced
by this command, but not the updated goals (they are
to be fetch by a separated [current_goals]). *)
