Description
Windows XP, Firefox 3.5.7.
Then '.removeClass("disabled")' called for '<tr class="disabled">' the result will be '<tr class=" ">'.
But expected result is '<tr class="">'.
Test case:
<html> <body> <script type="text/javascript" src="http://code.jquery.com/jquery-1.4.js"></script> Why removeClass add space if here is no class?!
<table> <tr class="disabled">
<td><h1 onclick="var tr = $(this).parents('tr'); tr.removeClass('disabled'); $('body').append('table row class after removeClass = \+tr.attr('class')+'\'<br/>')">click me</h1></td>
</tr> </table>
<pre> To fix: in "removeClass" method after elem.className = className.substring(1, className.length - 1); add if (elem.className == " ") elem.className = ""; </pre> <br/> </body> </html>

The length of the class once you've removed it does in fact seem to be 1 (ie the space mentioned in the original ticket).
Looking at core, this seems to be being done on purpose in the removeClass function around lines 1297-1282:
var className = (" " + elem.className + " ").replace(rclass, " "); for ( var c = 0, cl = classNames.length; c < cl; c++ ) { className = className.replace(" " + classNames[c] + " ", " "); }
Whilst I think a second review to confirm this behavior's need would be useful, I also question what (if any) impact it being in place has on a developer's ability to modify the class at a later stage as it is just afterall a space.

Flagging for second review.

This bug appears to be a duplicate of #5988. It was tested and fixed in the 1.4.2 release.
