This is the simplest fix. Note that this means that you don't get the
warning message on each command any more, but you get it when exiting
the shell (but you *can* exit it).

Maybe this different second argument (named `err' and indicating that
errors should be raised in `savehistfile()') was even intended to be
zero in that call -- otherwise it would be `1' in all calls, which
seems strange.
