Rename diff shown incorrectly when old name and new name start with the same letter

[ADTC]

The second one here is correct, but the first one looks like app/assets/variables.json was renamed to aaassets/variables.json (notice the triple A), when in fact the renaming was to assets/variables.json.

It looks like GitX is confused when both the before name and after name starts with the same letter or character.
