Huh --- I take that back; the "queries" and "errors" cases are implemented
totally independently of "all" mode. The "all" mode does work on a line
by line basis, and there's no good reason why it doesn't print blank
lines, except that somebody wasn't thinking very hard about where they
added the test. Will fix.

The documentation is wrong too, but not in the way I thought; it should
say that interactive input is never echoed by this feature, rather than
that it's "less useful" to turn it on for that.
