title: RegEx : Remove line breaks if lookbehind shows a lowercase
body: <p>I'm doing a CTRL+H (Find &amp; Replace) in Notepad++</p>
  
  <p>I want to find all Line breaks followed by lowercase characters in order to replace them with a space character ; thereby removing unwanted break lines in my text.</p>
  
  <p>Find : <strong>\r\n+(?![A-Z]|[0-9])</strong></p>
  
  <p>Replace : <em>insert space character here</em></p>
  
  <p>*Make sure you selected "<em>Match case</em>" and "<em>Regular expression</em>".</p>
  
  <p>It works perfect.</p>
  
  <p>Now, I'd like to do the same in Microsoft Office Word documents. Any clues?</p>
