} Looks fine.  I'll try to expand it when it appears.

Since writing it, I noticed that history aggressively directs output
to /dev/tty.  I haven't come up with any way to suppress that, and if
you run it without a tty the stderr pattern does not match.

However, that's not the only test that has problems if there is no tty:

I'm surprised that hasn't come up in anyone's automated build system yet.
