title: Powershell Regex: Replace only multiple spaces with tabs
body: <p>This is a Powershell question similar to what was being asked in this C# question:
  <a href="https://stackoverflow.com/questions/8460780/regex-replacing-multiple-spaces-with-tab">C# Question Link</a></p>
  
  <p>I have fixed width column data in a text file that are of variable length, so I'd like to delimit the data with tabs.  To do so, I want to use Powershell to read in the file, replace only multiple spaces with tabs using a Regex expression, keep the end of lines intact and output it to a temp file. I'll then rename it to the original.</p>
  
  <p>I've searched the web and only seem to be able to find bits and pieces.  Any assistance with this would be greatly appreciated!</p>
