By the way, how common this error is? Could you check if _your_ web
browser (Firefox, Internet Explorer, Opera, Konqueror, Safari, Chrome)
does show this bug or not, please?

I have found _a_ solution. Perhaps not the best one, but it works.
And IMHO gives / can give even better visual.

Current version (line wrapped for better visibility):
  <div class="header">
  <a class="title" href="...">GIT 1.6.1
  <span class="refs"> 
    <span class="tag indirect" title="tags/v1.6.1">
    <a href="...">v1.6.1</a>
    </span>
  </span>
  </a>
  </div>

Current CSS (relevant part):
  a.title {
  	display: block;
  	padding: 6px 8px;
  }

Current rendering:
  -----------------------------------------------------------
  |_GIT 1.6.1_ []                                           |
  -----------------------------------------------------------
  __v1.6.1__


Proposed code (line wrapped for better visibility, with CSS embedded,
which would change in final version of course). Only parts of style
related to positioning are shown.
  <div class="header">
  <a href="..." style="float: left; margin: 6px 1px 6px 8px;">GIT 1.6.1</a>
  <div style="float: left; margin: 6px 1px;">
    <span class="refs"> 
      <span class="tag indirect" title="tags/v1.6.1">
      <a href="...">v1.6.1</a>
      </span>
    </span>
  </div>
  <a href="..." style="display: block; padding: 6px 8px;">&nbsp;</a>
  </div>

Rendering with proposed code:
  -----------------------------------------------------------
  _|_GIT 1.6.1_ [_v1.6.1_]                                 |_
  -----------------------------------------------------------

I guess that instead of additional DIV element, we could use DIV for
.refs, or use "float: right" style with SPAN element. I have not
checked if other variations works: this one does.

What do you think?
