Directory rename should be displayed shorter

What steps will reproduce the problem?

1. In a new repo, create a file A1/B/C/F.txt in the given subdirectory path.
2. Rename A1 to A2 and commit.
3. Look at this commit's Path info in the log window.

What is the expected output?

{A1 => A2}/B/C/F.txt

What do you see instead?

B/C is duplicated: {A1/B/C => A2/B/C}/F.txt

This is especially annoying when B/C is a very long path.

What version of TortoiseGit and Git are you using? On what operating system?

TortoiseGit 2.1.0.0 and Git 2.8.0 on Windows 7.
