Like any text you post to PerlMonks, the answer is quite simple:
- Put <p>...</p> around non-code paragraphs
- Put <c>..</c> around code blocks.
That covers 95% of likely POD to be pasted and is very little work. Preserving links or emphasis is often not an issue and is only a little more effort when warranted.
Update: And then enclose the whole range in <blockquote>...</blockquote> to indent it apart from the rest of your node, of course.
