Re: [PATCH] Show binary file size change in diff --stat

> Previously, a binary file in the diffstat would show as:

> The space after the "Bin" was never used.  This patch changes binary
> lines in the diffstat to be:

>  some-binary-file.bin       |  Bin +123456B -12345B
> 
> The "+" item is the size of the new version, the "-" item is the size of
