Sorry, I was going to get to this last week. :-(

Can I suggest instead that we gut help.exp, and leave only a small set
of tests for basic functionality, instead of testing the multitude of
commands it currently tests?

[If someone want to argue to keep it as is, you also IMO need to argue
that every missing command and every new command also needs an entry
in help.exp (or equivalent elsewhere).  The maintenance burden is IMO
just too great.  Ergo my suggestion of just having minimal tests for
the basic functionality, but not testing so many commands.]
