Post Summary Text element spacing

One of the blogs I write uses a lot of terse headings, bullet points and quotations.

The automatically generated index page summary text for each post does not add spacing between the various elements - so My HeadingGets banged up against the first paraAnd the bullet pointsAlso get banged into each other…

Would it be possible to get the summary-text to simply include a trailing space for each distinct element or line-break?

The manual work around is to go and manually add whitespace after each distinct element - ummm.
