Merge branch 'jk/consistent-h'
"git $cmd -h" for builtin commands calls the implementation of the command (i.e. cmd_$cmd() function) without doing any repository set-up, and the commands that expect RUN_SETUP is done by the Git potty needs to be prepared to show the help text without barfing. * jk/consistent-h: t0012: test "-h" with builtins git: add hidden --list-builtins option version: convert to parse-options diff- and log- family: handle "git cmd -h" early submodule--helper: show usage for "-h" remote-{ext,fd}: print usage message on invalid arguments upload-archive: handle "-h" option early credential: handle invalid arguments earlier
