(** Running a command (given as a string).
- The 1st flag indicates whether to use "raw" mode
(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]). *)

No finished proofs will be re-opened. Instead,
we continue backtracking until before these proofs,
and answer the amount of extra backtracking performed.
Backtracking by more than the number of phrases already
interpreted successfully (and not yet undone) will fail. *)
