Re: ocaml 5

(Totally fine on 4.14.2.  I didn't realize we were behind.)

I am really not comfortable with moving to ocaml5.  It seems like many
in the ocaml world (those who produce software in ocaml, rather than
those who produce ocaml) think it's not really baked.  unison, at least,
has a policy of not accepting bug reports that aren't reproduced under
4.14.x.

I wonder if we should be having two versions.  But that is its own
negative.

Either way, it would be good to have the most recent production 5.x in
wip, to enable testing.   Doesn't look like that now.
