add line breaks between egXML examples

[alexduryee]

Currently, examples in egXML elements run together (e.g. from EAD3's abbr):

<didnote>File also contains materials from the
  <abbr expan="American Civil Liberties
  Union"> ACLU </abbr>
</didnote>
<c02>
  <did>
     <unittitle>
       <abbr expan="United Nations Educational,
       Scientific and Cultural Organization">
       UNESCO </abbr>
     </unittitle>
  [. . .] </did>
</c02>

There should be a line break between these two examples, so that it's clear that they're separate examples of abbr instead of one long one.
