Regex for merging lines if new line does not start with hyphen in Notepad++
<p>I am converting a book from pdf to notepad text. In pdf row length is fixed and that result half of sentences are transferred to a new row in text output. </p>

<p>I need a regular expression for <em>notepad++</em> that does the following:</p>

<p>If new line did not start with <code>-</code> merge it to previous line and do <code></code>&nbsp;(empty space).</p>

<p>Any other options that works for making text proper will be accepted.</p>
