There's a problem with this markup: it only works when there's a space
after the closing *, _ or =. So your example doesn't work as you typed
it - you have to type it like this:

  *bold* , _italic_ , and =monospace= .

Which, of course, looks awful because of the spaces before ','...

Also, why is the underscore used for italic? I've always thought that
one used /slashes/ for italic and _underscore_ for underlining. At
least that's how Gnus pretty-prints my mails, and it also seams more
logical to me.

I changed the Markup_nestled_emphasis class so do the markup like
this, but I'm afraid that it will change something else, because I
changed the huge regular expressions (which I didn't understand fully)
to much simpler versions... Perhaps someone could explain, what all
the look-ahead and look-behind does?

The changed class is this:

class Markup_nestled_emphasis extends BalancedMarkup
{
    var $_start_regexp = '[*_=\/]';

    function getEndRegexp ($match) {
        return "\\" . $match;
    }
    
    function markup ($match, $body) {
        switch ($match) {
        case '*': return new HtmlElement('b', $body);
        case '_': return new HtmlElement('u', $body);
        case '=': return new HtmlElement('tt', $body);
        default:  return new HtmlElement('i', $body);
        }
    }
}
