Document: undoing inside a focused zone does not require unfocusing

To test this fake_ide has also been improved with the GOALS command.
As for CoqIDE, ADDing a sentence does not force its evaluation.
The "advance 1 sentence" button is an ADD + GOALS.  If one of the
ADDed sentences is wrong, GOALS receives the error.  The GUI then
backtracks to a safe state id (sent by Coq).

fake_ide has GOALS (asserts that the goals call was OK) and FAILGOALS
to assert it fails and backtrack to a valid state. see unfdo022.fake.
