Right -- if this is while handling the error itself, then specbinding it
should do the trick...

So I've now pushed the change.  I've done some testing (to see whether I
can make it behave oddly if doing backtraces from an error and the
like), but everything seems to behave as before.

But we should be on the lookout for oddities in this area -- the
function may have been setting standard-output permanently for some
obscure reason...
