Currently you have to go to a line then find a link possibly multiple pages away to the parent then find the original source line in that rendered view. Having a link to the parent's annotation for that line on a line/block removes 2 potentially time consuming scrolling steps and would be a massive win for traveling back in time in the annotation view.

Or make links less informative.

  mpm at 22046 [^]  1 #require git

instead of

  ede at 12992  mpm at 22046  1 #require git

I don't like the latter because ede at 12992 looks like saying something related
to the line 1, but actually it is only the parent of 22046 in filelog.
