Hugo shortcode identation

[titpetric]

When using hugo shortcodes, a particular shortcode may be used as:

{{< warning success >}}
<some text here>
{{< /warning >}}

When using mdox fmt, the snippet above gets it's leading and trailing spacing stripped, making an unnecessary change to:

{{< warning success >}} <some text here> {{< /warning >}}.

Ideally the shortcodes would be treated in the same way as fenced code blocks, leaving the leading/exiting whitespace as is.
