Re: @above in analyses other than tran and dc sweep

Per Shalom's citation, "can" is the correct use here, since it is
a statement of possibility or capability.  "may" is incorrect,
since a simulator that failed to generate above events would
not be doing what was intended.

I think you're very confused about the usefulness of @above;
the very point was to be able to generate events for
non-transient (including the time=0 for transient).

Simulators do have a particular sequence of swept values,
and for circuits that have hysteresis (multiple operating
points), you can tell which direction the sweep was run.
