Re: [PATCH] gitk: Add "First parent" checkbox

"Ignore space change", "First parent", and the "Diff/Old Version/New
Version" radio buttons.  I would hate to see any of them be removed from
the diff pane.

Thanks, that's useful information.  Could you give example workflows
to illustrate this?  Here's an example:

   Toggling between "Diff/Old version/New version" with a single click
   allows one to compare the preimage and postimage of a patch visually.
   It makes what changed much more obvious.

   Historically these have been radio buttons on the top-left part of
   the diff pane.  If they move, it might be hard for people already
   familiar with gitk to find them.

   The preimage/postimage toggle is a useful and novel feature, and it
   is greedy with respect to screen real estate (a few extra diff
   lines can go a long way), so it would not be good to hide it in a
   separate "more diff options" toolbar.

The case for one-click "diff against parent" is less clear.  Is it
that it gets toggled in practice often (i.e., avoiding pointless
repetitive actions)?

Hope that helps.
