Ah-hah!

So what we really want here, I guess, is for the test script to suppress
reading of ~/.inputrc, on the same principle that it suppresses reading
of ~/.psqlrc.  A quick look at the readline docs suggests that the
best way to do that would be to set envar INPUTRC to /dev/null --- could
you confirm that that works for you?

Hm.  I wonder how it is that that leads to ignoring the TERM environment?
Still, it's just an academic point if we can suppress reading the file.
