Add option to jump to specific parent of merge commit

[jcarius]

I find the graph view of the log very helpful for understanding what has happened on a specific branch. However, a merge commit may bring in a lot of commits in the graph view that may not be of interest (or the merge message itself has enough information already).

Instead of scrolling over lots of commits, it would be great to be able to directly jump to that parent of the merge commit that I'm interested in.

For example in the following graph, it would be great if one could jump to f7449ed5 directly, for example by clicking on its commit id which is mentioned on the line Merge: f7449ed5 50b0d85c or by clicking on any of the | bars that lead to it.

I know tig something like that, we should see how they do it, shouldn't be too conplicated.
