["Vasil Dimov via GitGitGadget" <gitgitgadget@gmail.com>]

 * override a possibly user-customized format.pretty that would render git
   log output unparsable by git range-diff
   
   
 * don't use negative string precision, e.g. "%.*s", -5, "foo"
   
   

Changes since v1:

 * Fixed a typo in the commit message (found by Taylor Blau)

     -    If the supplied integer for "precisoin" is negative in
     +    If the supplied integer for "precision" is negative in
          `"%.*s", len, line` then it is ignored. So the current code is
          equivalent to just `"%s", line` because it is executed only if
          `len` is negative.
