I've removed those GBS anchors without problem.
I'll also note that the <div> and <figure> tag also suffer the same lack of Beautification if there's an <a></a> tag in there with an image (I usually see it between the <div> or <figure> start tag and the <img> start tag it contains. For instance:
Code:
<div id="fig_1"><a></a><img src="../images/00005.jpeg" alt="Thror's Map" class="imgfull"/></div>
will not beautify (ditto for the <figure> version). But, delete the <a> tag pair and it beautifies just fine.
