Actually, that cannot be the whole story. Because evaluating the
:eval forms in the mode line arranges for catching the errors (and the
above text in *Messages* is the evidence that it works here), and so
we should have still run redisplay_window to completion after that,
which includes restoring the buffer's point to its original value.
Hmm...
