title: "Case folding" error trying to clone a mercurial repo
body: <p>I try to clone a local mercurial repository on windows.</p>
  
  <p>I get this error:</p>
  
  <pre><code>   C:\temp\toolkit1.1&gt;hg clone \src\toolkit
     destination directory: toolkit
     updating working directory
     abort: case-folding collision between sdk/Api.h and sdk/api.h
  </code></pre>
  
  <p>It looks like I changed capitalization of API.H at some point, but I don't know how to resolve this. Any tips?</p>
  
  <p>I am using the version: 1.2.1</p>
