This new functionality is great except when it truncates the commit 
description needlessly.

When running gitk full-screen on a large display, I have a commit 
information window that is much wider than needed for the truncated 
parent information. Leaving me with a lot of whitespace that should be 
used for the commit descriptions.

On a related nit: some of the diffs I'm viewing have lines longer than 
the width of the commit information window and it's annoying that gitk 
wraps the line rather than providing horizontal scrolling.

How about implementing horizontal scrolling in the commit information 
window when the commit text or the diffs are wider than the window and 
not truncating the commit descriptions?
