[Plugin: WordPress HTTPS (SSL)] Upgrade results in malformed log{in,out} URL

My sidebar has the following HTML:

<h2 class="menuheader">Utils</h2><div class="menucontent">			<ul>
			<li><a href="http://hashbang.ca/wp-admin/">Site Admin</a></li>			<li><a href="http://hashbang.ca/wp-login.php?action=logout&_wpnonce=3862b608b7">Log out</a></li>
			<li><a href="http://hashbang.ca/feed/" title="Syndicate this site using RSS 2.0">Entries <abbr title="Really Simple Syndication">RSS</abbr></a></li>
			<li><a href="http://hashbang.ca/comments/feed/" title="The latest comments to all posts in RSS">Comments <abbr title="Really Simple Syndication">RSS</abbr></a></li>
						</ul>

When I turn on WordPress HTTPS, the first item in that unordered list gets corrupted:

<h2 class="menuheader">Utils</h2><div class="menucontent">			<ul>
			<li><a href="http://hashbang.ca/wp-admin/">Site Admin</a></li>			<li><a href="http://hashbang.ca/wp-login.php?action=logout&_wpnonce=3862b608b7">Log out</a></li>
			<li><a href="http://hashbang.ca/feed/" title="Syndicate this site using RSS 2.0">Entries <abbr title="Really Simple Syndication">RSS</abbr></a></li>
			<li><a href="http://hashbang.ca/comments/feed/" title="The latest comments to all posts in RSS">Comments <abbr title="Really Simple Syndication">RSS</abbr></a></li>
						</ul>

I keep my site in a git repo, and I tracked the error down to this set of changes:
