Re: 23.0.50; savehist save invalid syntax

[Richard Stallman]

    With this much complexity, my temptation would be to provide a
    print-readable function (or an optional argument to an existing printer)
    that signalled if it  were asked to print something that has no read
    syntax.

I wouldn't mind adding that feature if someone wants to do it.
It should be controlled by a variable.

Meanwhile, does my fix work?
