title: How to determine why GitVersion chose a specific base version?
body: <p>I am using GitVersion (version 3.5.3 if it matters), and getting some unexpected results; specifically the produced version has an unexpected commit count portion. Looking at the log I can see the commit count is calculated correctly, but the base version used by GitVersion is wrong (or at least not what I thought it would be).</p>
  
  <p>However the log file for GitVersion is less than helpful, it just lists a series of tags, then a long list of merge bases, and at the end it just says which base version it decided to use.</p>
  
  <p>Can GitVersion let me know somehow why it chose that specific base version?</p>
