In diff-view, don't shorten numstats unnecessarily

[wsakernel]

diff_open() uses "--patch-with-stat" which implies "--stat" which cuts the num-stats down to 80 chars. This cuts down filenames in most of the cases, which I find hard to work with since my terminals easily have 200+ chars, so I am missing needed information although the space is there. I'd love to see diff_open use something like "-p --stat=my_current_terminal_width" instead of "--patch-with-stat".

So now there's a prototype, but I am not sure I see how much information it adds.

As pointed out by @eMPee584 this breaks resizing so it will have to be reverted for now.

Delightful - fixes dynamic resizing and creates abundant happiness throughout the cli realm ×)
Cheers!
