help: convert git_cmd to page in one place
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.
