replaceWith() accept callback for content

[jablko]

I wish that the replaceWith() function accepted for its "content" argument - in addition to a string, or an element, or a jQuery - a callback which would return one of the three existing types of argument.

My application is I am trying to autolink strings like "r1234" to our project's repository browser. I don't want to autolink strings in <textarea> elements:

$(document).ready(function ()
  {
    $(':not(textarea)').contents()
      .filter(function ()
        {
          return 3 == this.nodeType;
        })
      .replace(function ()
        {
          this.nodeValue
            .replace(/\br(\d+)\b/g, '<a class="external text" href="http://code.google.com/p/qubit-toolkit/source/detail?r=$1">$&</a>')
            .replace(/\brevision\s*#?\s*(\d+)\b/gi, '<a class="external text" href="http://code.google.com/p/qubit-toolkit/source/detail?r=$1">$&</a>')
            .replace(/\bissue\s*#?\s*(\d+)\b/gi, '<a class="external text" href="http://code.google.com/p/qubit-toolkit/issues/detail?id=$1">$&</a>'));
        });
  });

It's easy to write a small plugin to do this, so it's not really appropriate for jQuery core.
