D. Ben Knoble 129b3632f3 builtin: also setup gently for --help-all ...

Git experts often check the help summary of a command to make sure they
spell options right when suggesting advice to colleagues. Further, they
might check hidden options when responding to queries about deprecated
options like git-rebase(1)'s "preserve merges" option. But some commands
don't support "--help-all" outside of a git directory. Running (for
example)

    git rebase --help-all

outside a directory fails in "setup_git_directory", erroring with the
localized form of

    fatal: not a git repository (or any of the parent directories): .git

Like 99caeed05d (Let 'git <command> -h' show usage without a git dir,
2009-11-09), we want to show the "--help-all" output even without a git
dir. Make "--help-all" where we expect "-h" to mean
"setup_git_directory_gently", and interpose early in the natural place
("show_usage_with_options_if_asked").

Do the same for usage callers with show_usage_if_asked.

The exception is merge-recursive, whose help block doesn't use newer
APIs.
