commit 992aeed80b0a6ef1d60ce01df52f3397c3274f35
Author: Tom Tromey <tromey@adacore.com>
Date: Thu Aug 11 10:07:18 2022 -0600
Use ui_out_redirect_pop in more places
This changes ui_out_redirect_pop to also perform the redirection, and
then updates several sites to use this, rather than explicit
redirects.
