This still leaves a chance of going wrong: when user explicitly gives
"--paginate", use_pager will be 1, but commands like "git init" does
not have RUN_SETUP*. So when setup_pager is called later on, it will
mess things up. This could be solved completely (indeed I have a patch
under testing), but it would require unset_git_directory(), making
this series a bit longer :(
