In the "blob" view, I think it does make it more discoverable that
these line numbers are links, so I personally think a.linenr:hover
part is an improvement.  I am not sure about other three changes
adding any value, though.

Actually, when viewing the blame view, this is even worse, as it
seems to always overlap.  The background color ought to be enough
cue without being overly distracting, I would have to say.

Jakub?  Comments on any other points I may have missed?
