diff- and log- family: handle "git cmd -h" early
"git $builtin -h" bypasses the usual repository setup and calls the cmd_$builtin() function, expecting it to show the help text. Unfortunately the commands in the log- and the diff- family want to call into the revisions machinery, which by definition needs to have a repository already discovered. Strictly speaking, they may not need a repository only for parsing "-h", but it is a good discipline to future-proof codepath to ensure that setup_revisions() is called after we know that a repository is there. Handle the "git $builtin -h" special case very early in these commands to work around potential issues. Signed-off-by: Junio C Hamano <>
