Already tried it and it seems to be working just fine. Thanks for making it happen so quickly.
The only things that worry me a bit are potential usability problems.
The styling of the numbers, for example, is the same as the rest of the text in the line, which is not necessarily bad, but it looks to me like they get a little bit lost. I tried removing the bold styling and putting the number between parenthesis to make them look like the totals at the top of the page (Drafts, Trash, etc.) and result were promising.
Also there are no confirmations of what it is that the + / – signs and the numbers do or represent; though that should be obvious for many users, it will surely not be obvious for everyone. Using TITLE attributes I found a possible workaround, at least when you hover over them.
<span class="expand_link"><a title="Collapse subpages" href="javascript:void(0);" class="minus">[children]</a></span><span title="2 subpages" style="font-weight:normal;">(2)</span>
