Focus on blame view and correct line

[ouuan]

• Focus on the blame view instead of the file content when it is opened and after going to the previous commit. (might be configurable)

• Go to the correct line after going to the previous commit. The line number is provided in the line porcelain.

  Alternatively, implement something like fugitive: https://github.com/tpope/vim-fugitive/blob/dac8e5c2d85926df92672bf2afb4fc48656d96c7/doc/fugitive.txt#L75-L83

  use to open up the commit, select the corresponding - line that you care about, and press twice more to reblame at that line. Viewing the commit also gives you additional context as to why the line changed.
