blinded/unblinded message every turn while engulfed wearing the Eyes

I think this was From a bug report, but I cannot find the report
anymore.  Perhaps I noticed it while doing something else.  In any case,
every turn you're engulfed in, say, a dust vortex wearing the Eyes of the
Overworld, you get the "can't see"/"vision clears" message pair.  This
patch modifies the behavior to only display this the first turn.  Other code,
partially related to B01003, already deals with the puton-remove cases.
Since B01003 is only in the trunk, this fix is also only in the trunk.
