Wrong formating of lists

[adkas]

wortsammler v.2.0dev removes an addtional line in lists.
This causes difficulties to use Pandoc v2.6, which needs this empty line.

Thank you if you can fix this issue.

the problem is that pandoc changed the format of definition lists in pandoc 1.12. During this transition process some documents got corrupted, which need to be fixed manually.

I wil turn on compact_definition_lists which restores the behavior of 1.12 in the next dev release of wortsammler.
