title: Magit is very slow when committing on Windows
body: <p>Magit takes enormously long time to commit a file. Absolutely disproportional to any other task - can take several minutes, or else I give up and commit it from the shell. Is there any reason to it? How can I debug it?
  Interestingly, if I kill <code>*magit-process*</code> buffer (the one which has to interact with git process), and then continue with the task, then everything works. But there are no error messages in that buffer, just the command itself.</p>
