[PATCH 06/12 v2] apply: run setup_git_directory_gently() sooner

["Nguyễn Thái Ngọc Duy" <pclouds@gmail.com>]

As v1.7.2~16^2 (2010-07-14) explains, without this change,
“git --paginate apply” can ignore the repository-local
“[core] pager” configuration.

 This is a replacement for 4ce097c (apply: run
 setup_git_directory_gently() sooner) in pu, branch jn/paginate-fix,
 which fixes prefix loss in 4ce097c.

 All tests seem to run ok for me.
