> [PATCH] gitweb: make leftmost column of blame less cluttered.
>
> Instead of labelling each and every line with clickable commit
> object name, this makes the blame output to show them only on
> the first line of each group of lines from the same revision.
>
> Also it makes mouse-over to show the minimum authorship and
> authordate information for extra cuteness ;-).
