Depending on the chosen format of help pages, git-help uses function show_man_page, show_info_page, or show_html_page. The first thing all three functions do is to convert given `git_cmd` to a `page` using function cmd_to_page. Move the common part of these three functions to function cmd_help to avoid code duplication.
