git --paginate: do not commit pager choice too early
When git is passed the --paginate option, starting up a pager requires deciding what pager to start, which requires access to the core.pager configuration. At the relevant moment, the repository has not been searched for yet. Attempting to access the configuration at this point results in git_dir being set to .git [*], which is almost certainly not what was wanted. In particular, when run from a subdirectory of the toplevel, git --paginate does not respect the core.pager setting from the current repository. [*] unless GIT_DIR or GIT_CONFIG is set So delay the pager startup when possible: 1. run_argv() already commits pager choice inside run_builtin() if a command is found. For commands that use RUN_SETUP, waiting until then fixes the problem described above: once git knows where to look, it happily respects the core.pager setting. 2. list_common_cmds_help() prints out 29 lines and exits. This can benefit from pagination, so we need to commit the pager choice before writing this output. Luckily ‘git’ without subcommand has no other reason to access a repository, so it would be intuitive to ignore repository-local configuration in this case. Simpler for now to choose a pager using the funny code that notices a repository that happens to be at .git. That this accesses a repository when it is very convenient to is a bug but not an important one. 3. help_unknown_cmd() prints out a few lines to stderr. It is not important to paginate this, so don’t.
