Before this patch, something like "git help tutorial" did not work,
people had to use "git help gittutorial" which is not very intuitive.
This patch uses the "is_git_command" function to test early if the
argument passed to "git help" is a git command, and if this is not the
case then we prefix the argument with "git" instead of "git-".
This way, things like "git help tutorial" or "git help glossary" will
work fine.
The little downside of this patch is that the "is_git_command" is a
little bit slow.
