Yeah, I don't see much value either.  It's a constant source of
update pain.

I've found the bits of selftest.exp that interact with SIGINT
useful in the past, as that interacts with readline's SIGINT
handler.  IIUC, that caught a bug in some local version of my
console work earlier in the year.  So I'd prefer to keep those
bits.  But I wouldn't miss do_steps_and_nexts for sure.
