title: Diff tool (for comparing minified files) which can ignore small changes (lines with one or two characters changed)
body: <p>I sometimes want to diff the output of JS builds. The files are minified, so I first prettify them. The problem though is that sometimes small changes in the input yield <em>hundreds</em> of trivial changes in the output file, due to minification process assigning different variable names all over the output file.</p>
  <p>I would like a diff tool that can ignore those small changes (that are typically 1 or 2 character diffs) and only show bigger diffs.</p>
  <p>Is there a tool like that, or can Beyond Compare be configured like that?</p>
  <p>A typical diff I'd like to ignore looks like this:</p>
