diff: diff.context configuration gives default to -U
Introduce a configuration variable diff.context that tells Porcelain commands to use a non-default number of context lines instead of 3 (the default). With this variable, users do not have to keep repeating "git log -U8" from the command line; instead, it becomes sufficient to say "git config diff.context 8" just once.
