[PATCH] gitweb: pull ref markes pull out of subject <a> tag

Since 4afbaefffa9095fe1391b4b61289a7dc954e9f7b ref markers that
accompain the subject in views such as shortlog and history point to
something different from the subject itself. Therefore, they should not
be included in the same <a> tag.

Benefits of the change are:
* better compliance to the XHTML standards, that forbid links within
  links even though the restriction cannot be imposed via DTD; this also
  benefits visualization in some older browsers;
* when hovering the subject, only the subject itself is underlined; when
  hovering the ref markers, only the text in the hovered ref marker is
  underlined; previously, hovering any written part of the subject
  column led to complete underlying of everything at the same time,
  with unpleasing effects.

The next step would be to find a way to layout decently the case when
some shortlog entries have a _humongous_ amount of ref markers. See
for example http://git.oblomov.eu/acecad/shortlog

I honestly doubt these cases happen in normal git repositories, but it
might still be worth taking them into consideration. Possibilities
include hard-limiting the title column maximum width (in browsers for
which the corresponding attributes and rules work), manual insertion of
hard line breaks <br/> every n-th ref marker, or something more dynamic
such as hiding most of the ref markers when they are more than, say, 5,
and showing them on hover.

Suggestions? Comments?
