I don't think this is the right way to handle this.  There's other
behaviour here that needs to be suppressed if this is inline content,
such as the call to cgit_set_title_from_path(), and I don't think we
want the object header above the readme content.

Additionally, if read_sha1_file() fails we'll output another page header
here.

Since it's not much code overall, I think we probably don't want to
reuse print_object() for the inline rendering, but can instead just do
the render & mimetype lookup and then do:

	if (render)
		render_buffer(render, basename, buf, size);
	else if (mimetype)
		include_file(sha1, path, mimetype);
	else
		print_buffer(basename, buf, size);
