Trailing whitespace on git diff output.

Hello,

Today, while redirecting git diff's output to a text file, I noticed git diff leaves a trailing whitespace between different deltas of the same file (the line that separates two different deltas). For example, committing a file with the following content: --- test

test ---

then changing it to the following: --- test test

test test ---

committing and diffing it, leaves a trailing whitespace on line 8 of the diff output.

Is that expected behavior? I'm using git 2.1.0.

Sorry for taking your time,

Adria
