From: Johannes Schindelin <[email protected]>
As pointed out by Elijah Newren, tbdiff has this neat little alignment
trick where it outputs the commit pairs with patch numbers that are
padded to the maximal patch number's width:
1: cafedead = 1: acefade first patch
[...]
314: beefeada < 314: facecab up to PI!
Let's do the same in range-diff, too.
