[3.13] Support the "pager" binary in _pyrepl (GH-122878) (#124242) Support the "pager" binary in _pyrepl (GH-122878) Debian (and derivatives) provide a /usr/bin/pager binary, managed by the alternatives system, that always points to an available pager utility. Allow _pyrepl to use it, to follow system policy. This is a very trivial change, from a patch that Debian has been carrying since 2.7 era. Seems appropriate to upstream. https://bugs.debian.org/799555 (cherry picked from commit 426569eb8ca1edaa68026aa2bab6b8d1c9105f93) Co-authored-by: Stefano Rivera <[email protected]> Co-authored-by: T.
