Fix raw html reference issue (#585)

Preserve the line which a reference was on to prevent raw HTML indexing issue. Fixes #584.

Prevent raw HTML parsing issue in abbr and footnotes

Peserve abbreviation line when stripping and preserve a line for each footnote block.  Footnotes should also accumulate the extraneous padding.

Test extra lines at the end of references

Strip the gathered extraneous whitespace

When processing footnotes, we don't actually care to process the extra whitespace at the end of a footnote, but we want it to calculate lines to preserve.
